My car radio turns on but then its cuts to nithing then it starts again then stops , now my battery protection convection is unavailable , my battery draining !!
Thank you for posting this comment. I just tried it and it worked. I didn’t even have to replaced the fuse. I just pulled it and put it back in. Who knows how much money you have saved me….

Hi, thanks for the video, very eye opening. I'd like to ask what I think is very important regarding the modules that connect to the radio in the cockpit. Are the fibre optic cables navigation, audio gateway, voice module, etc multi-mode or single-mode? I'm asking because I removed the Bluetooth dongle from inside my armrest compartment to free up space for my actual phone, and that caused the radio to stop working. I'm just wondering if I can splice the in and out cables to close the loop. Thanks.
I bought male and female loop connectors...but do not see a fiber optic plug going into the teleaide module...there is a plug, but it is not the same as the loop and the wires going to it are black... help me please!
Greatttt men thank you so much for this INFO! But for the mercedez Ml320 the Bluetooth system is just behind the front desk and you can plug in there!!
my radio unit does the same. the problem that the AGW and the Radio draining the battery, i took out fuse 6 in the trunk and fuse 26 near the driver side. does it worth to buy the bypass lollipop and give it a try, or need to replace the AGW. Thank you.
Hello thank you so much for this video. I have a 2003 e320 and the radio/cd player intermittently stops for 5 to 10 seconds and ive just placed an order of the lollypop. Where do you suggest i bypass first?
You could bypass voice module if your car has one. Otherwise you need to replace the audio gateway and find out because you can't bypass the audio gateway.
@@HiTechElectronic so i got the fiber optic loop and attached it in the back of that silver box and it did the trick now it doesnt skip! Thanks to you brother! Another question if you dont mind answering my steering wheel for e320 is heavy I believe its a broken belt somewhere how much should it cost if i was to get it fixed?
Hello Mister, thank you for detailed guide! Very useful. I tried searching for my problem here but didnt find any answer - My 219 Cls with PremiumAudio(HarmanKardon) should have the option for SurrroundSound/Logic7 music modes, but it lacks it. Only the fader and balance, bass and treble can be controlled from Comand. Do you know if that could be a problem with Audio Gateway, or more likely to be Comand's problem? Have a great new year's start! Cheers.
Thanks for the video! I’m having the same issue you mentioned with the tail light module. My audio will cut out intermittently for a few seconds then turn back on. Do you still think that’s an issue with the tail light module? Or the voice module? If I discover that the issue is the tail light module do I need to replace it? Or can I leave it bypassed?

Hi I have been using the bypass but I noticed that when I removed the fibre optic cable from the audio gatewayi noticed there was no red light coming through the cable all the other were showing a light ,what do you think.
Great!! Let me ask you a question: what if a change the unit for a new one that comes with CarPlay, this problem will go away or I still have to bypass ??
@@HiTechElectronicI understand there is a fuse at the back of the radio/CD player at the back. Perhaps that might be what I need to check? I checked all other fuses and they are okay.
@@HiTechElectronicThere is a soft humming sound coming from what I suspect is the radio. Do you still think it's faulty? I am trying to remove it for a close inspection.

Hey there again you wouldn't be able to tell me how to make my cars fade ability work on my 55 w211 Mercedes it has the same stereo I have a 2006 model car and it will let me adjust the fade front to rear but the 2004 car will not exact same stereo and both cars. And I was wondering if you might be able to tell me how to change this through the developer menu or engineering menu?
the head unit in my 2008 cls63 recently started turning off then on randomly. along with this came a "popping" or "cracking" sound from the speakers every 10 seconds or so. considering the fact that im getting cracking and popping along with the radio shutting itself off, it's more than likely the amp, right? anyone on here have any input? all fuses are fine
For the tele aide module will it need flashing or programming for installation.if im switching it out with one from the junkyard???or is plugging ready ?direct swap??
Purchased tele aid and audio gateway module..the orange sticker says "once installed this control module contains vehicle specific data.installation in another vehicle is strictly prohibited .please refer to service literature for proper service and replacement procedure" which is for the tele aid module.the module was pulled from another car same year same engine .when I purchased the car it didn't come with books or service manual ..
Have any of you ever encountered a command system that will cycle through the Mercedes’ logo until the power button is pressed, then once turned on says “system (or device can’t remember exactly) unavailable” and then turns off again. Probably one of the modules mentioned in the video? 2005 S430 for reference, thanks!
In that box is a small fan that stays on when my doors are locked and car is sleeping. Thats why my battery is very weak.. also navi is not working.. 320cdi '07.. where i can find new one?
I changed the car navigation from the back and even the audio gateway which were used on another w211, and i still got the same problem, it turns on and off, could be the voice module or the taillight module?
Hello. My radio occasionally works, but more often lately it doesn't work at all .No logo and CD changer doesn't come out either. Does that mean the radio head has a loose connection or needs replacing. Thanks
I have a feeling it is the cd player on mine when I turn the ignition on I can hear the CD player trying to select a disc and it seems to be trying all the 6 slots, hopefully I will sort it out over the weekend.
@@bijandaneshmand3659 hi I have done that, some months back I noticed the radio would come on in the morning after the car has been parked up over night then if the car was driven locally then park up the drive again and park up then drive again the radio would not come on at all until it had been parked up for several hours,but now the radio does not come on at all ,sometimes it will show the logo then go of,it's so frustrating, do you have any other ideas. Regards pete
Okay i did it got my sound and radio back. I bipassed all componets it was voice module. I still have sos error but command unit and cd changer sound work
Great video I have a 07 R320 which radio freezes. I have sound but radio will not change station, can't change any function but does have volume volume control freezes as well. Any advise what to check? I have a code audio gateway D241 cd/dvd cant be ejected.
Hello, how are you? I had a problem with the battery, it drained quickly, so I took it to the Mercedes maintenance specialist, and something was separated in the trunk , and the problem disappeared, but the radio became stuck on the Mercedes logo. Do you expect the problem from the navigation unit?
I have a ml350 and the system turns on the logo doesn’t go away non of the buttons work but the cd audio plays I just can’t use the nav/backup camera/radio what do you think the problem is?
I have a E350 2006 Benz and my battery keeps draining. We think we figured it out and believe that it’s the navigation system in the trunk and radio. But someone said I may have to look into taking the car to the dealership about the audio gateway for the radio. Any suggestions?
this probaly works but i tried following the steps but being that i didnt have the tools .. i juss disconneted both the main battery witch is in the rear and the conventional fuctions battery located in the front hood and put it back together my radio and navigation was operational again ...this is what i call a hard rest but it most certainly worked
Hi there, I purchased a GL450 2009 and the cd player took the 6 cd's with no problem, but, after a family trip it didn't eject them, so, I took the command control out trying to fix it, couldn't do anything since is too complicated for my electronic knowledge, so, I put it back, hook up all the connections exactly like they were before, but, now it doesn't turn on at all,, can you please advisement? Thanks in advance
How do you bypass the teleaid module when the fiber optic loop is different from the other ones? What fiber optic loop do I need for the teleaid for a 2008 e350 Mercedes.
CLK320 2004 does not have Gateway. Most likely the problem could be a bad amplifier or CD Changer. You are welcome to send both of them in for a free evaluation.
@@HiTechElectronic Hi, thanks for replying, so this what is happening. I turn the power on, logo lights up no problem. It starts to click, still no audio, if i turn the volume the audio comes on, then stops, still clicks. also the command switches/ push buttons wont work correctly.
Thank you for sharing this video . I have e320cdi 2004 model. It has identical COMAND as in this video. Only when driving around it stops music or phone with an electrical beep for a few seconds then comes back on. Drives me crazy. Anyone have the same problem?
Yes, ive been dealing with this problem for over 2 years now. Its a high pitched beep and sometimes it doesnt beep but cuts out for like 2 seconds. Mine does it close to every one minute. Im geussing it has something to do with teleaid trying to send my location out and it failing but thats just a geuss. I have a 2006 e350 with the same type of command unit. Have you found out what the issue was?
@@RyLokey Hi thanks for the reply. I never took the car to be fixed. Just lived with the same problem for over 6 years. Then suddenly last year about April it stopped and has never given me a problem again! I don't know what fixed it.
@@MrOogats Haha thanks for giving me hope! I notice it less frequently now, but maybe its because im used to it. Although whenever im driving someone who hasnt rode in my car before i notice it a lot more haha. Im hoping it goes away like yours did. I appreciate the reply!
@@Geodickerson Unfortunately I never did. I just put up with it for 9 years! Then one day it just started playing ok and never broke down for almost 2 years until 10 month ago it stopped altogether.
Very good presentation! I have a problem with the CD changer - sometimes it works well and then just stops and shows a message that says 'Error CDx" where x is 1 up t0 6. what can the problem be?

I own a 2005 Mercedes C320 4matic, I don’t have sound I check all fuses and all are in good condition,, but where I can found the amplifier? Thanks for your help.. I
Thank you. The video is very helpful. I have a 2007 ML350 with Harmon Kardon upgraded sound system. When I turn on the care, everything works, but after a minute or two the sound cuts off. I have tried replacing the Amp and the Audio Gateway under the seat with used ones I found I found on eBay, but the issue could not be fixed and I have tested the Command unit and that is fine as well. I did not however use a scanner to reset things after the installation of these components. Do I need to do that before these parts start working or could the issue be something else I am missing. Thank you in advance for your response.
Me too i got 2004 e320 4matic with harmon system. I replaysed voice m9dule and cd changer sound is back bit always i got this module nect to tele aid on right side what is it cant find what it is looks like amp idk. On your video you have an empty slot on the right mine has the amp l9oking module their what is that? Maybe thats problem? Idk can you please help?
thanks for your advice too the same thing happened to me after I changed the car battery no longer turns on the radio does not even open the drawer where the cds are not c "not even light keys fuses are ok I tried the optical sypass nothing please give me some advice thanks
@@antoniocalabresi You need to bypass the components in the trunk one by and and also the CD changer in the dash board, if still have the issue then most likely the problem could be the Audio Gateway module in the trunk or it is missing 12 volts power.

The navigation system in my E350 2007 Mercedes has been functioning very well - until suddenly today it stopped. Nothing untoward, no recent service, no interruption in audio, sirius is working well, CD player is ... Your video addresses all of these issues, but spends little instruction on how to check for nav connectivity. Any suggestions?
Thanks for sharing this information !! I have a c230 2005 and I just added a Sirius unit, for satelite radio. May I used the roof ( back ) antenna to connect to the satelite radio? the antenna is the small black stick in the back. I think this was used for the tele Aid ( not installed in my car) Also I'd like to know where I can get the cable terminal , ( what side of the vehicle) I saw like a double connection in the left back close the the fuses. thank you !
where is that cable for that bypass to mount at a mercedes ml 320 of 2007 because have the same problem and is identical the same radio. have taken apart all the back upholstery and see so no system
my friend i love you u tube video. I have a 2006 cls500 mercedes and the navigation is not loud any more, the navigation works, the maps also works but we dont know how to have it loud again, it also says to us that the navigation is not actived what do you think i have to do?

hey, i have a 2007 ml350 and when i turn the car on, the audio works then it cuts off after two minutes. I used the bypass loop for the amplifier and tele module checked the fuses but it still doesnt work.
Hey guys, I've had a 2008 Mercedes Benz E350 for 2 years now. The Harmon kardon Logic7 sounded amazing. Until one day my CD changer stopped working while I had CDs inside . I've been reading forums and some people said to remove the fuse for AGW, the CD changer and the radio. I followed the steps took the fuses out, put them back, and at the end the CD changer started working again. But ever since I removed the fuses and put them back into place, my sound has not been the same. I used to get powerful bass from the front speakers, and the subwoofer , and an awesome clear surround sound experience. So much question is do I have to go into engineering mode to get the sound back, or what do I have to do to get the sound? Because I believe that after removing the fuses I must've messed up a component in the radio system that has to be readjusted. I still get sound, but it's not the same as it used to be before I removed the fuses. Sometimes I try, and I put the bass to maximum, and nothing happens. Guys please help me.
We have Mercedes 2008 GL450 and the audio system shows a Mercedes sign upon turning on but the then stays on with audio radio working but not the steering wheel controls and backup camera during summer time. However during winters when the temp drops the system starts to function normally on and off. Could you please give your expert opinion and help
I have a 2007 E350. When I insert the Nav DVD in the trunk my screen says to insert the disc. It my Nav not able to read the disc. Maybe it's not recognizing the cd has been inserted. What suggestions do you have for this error. Thank You
I have a 2005 E500, after a dead battety and some moisture in the trunk. My radio stays on but no sound. It's stuck on the logo. It does not turn off. I checked all fuses and tried re-setting but no luck. You have any idea what could be the issue? The radio/nav worked fine before the battery went dead. I also noticed the unit where the navigation cd goes. The lights are flashing.
@@HiTechElectronic so I got the tool and checked the nav module and cd changer up front and still the same. Radio turns on then shuts off. I did notice that my 5 amp fuse number 85 keeps blowing out. Am I missing something here?
Hello, my comand unit NTG1 does not start when i push the Power button. Sometimes it does, but most times not. Most times, I would pull out FUSE 26 from the Radio Unit, and it would start. Now, even if I do that, it still wont start. I have bypassed the Navigation unit and the Tele-aid in the trunk, and still does not start. I suspected the AGW but after seeing your video, and listening, I think for sure it's the comand unit. PS: I don't have CD changer. Any sugestions?
My 2002 s430 radio display is not working. The radio and all the functions work fine but no display. I can listen to the radio and changes station but the display is black. Any suggestions?
Ok so I narrowed it down. I think it’s my Audio gateway I checked all the other audio components with the fiber optic. Smh and the radio still doesn’t work but I keep getting static and then the radio just shuts off. I also found out my left taillight has been getting rain on so I believe the rain has messed the audio gateway up so no radio until I get that fixed, by any chance do you know how much it will cost to get a audio gateway installed for a 2008 e350?

Hi,
Thanks for the video.
Is there a way to add Bluetooth functionality ?
Mine is Japanese command and it doesn't have Bluetooth or aux.
Question completely different from the radio. My key fob is stuck in the ignition I can turn on the car but I can't take the key out any suggestions? Please and thank you !

Hey there again you wouldn't be able to tell me how to make my cars fade ability work on my 55 w211 Mercedes it has the same stereo I have a 2006 model car and it will let me adjust the fade front to rear but the 2004 car will not exact same stereo and both cars. And I was wondering if you might be able to tell me how to change this through the developer menu or engineering menu?
Were do you buy the by pass module
Thank you for the video
Do you guys fix ecm for 06 e350?
Thank you
Yes, we do repair them.
the head unit in my 2008 cls63 recently started turning off then on randomly. along with this came a "popping" or "cracking" sound from the speakers every 10 seconds or so. considering the fact that im getting cracking and popping along with the radio shutting itself off, it's more than likely the amp, right? anyone on here have any input? all fuses are fine
For the tele aide module will it need flashing or programming for installation.if im switching it out with one from the junkyard???or is plugging ready ?direct swap??
Purchased tele aid and audio gateway module..the orange sticker says "once installed this control module contains vehicle specific data.installation in another vehicle is strictly prohibited .please refer to service literature for proper service and replacement procedure" which is for the tele aid module.the module was pulled from another car same year same engine .when I purchased the car it didn't come with books or service manual ..
Will install audio gateway module since it dont have any warning and wait for your response on the tele aide module .
Have any of you ever encountered a command system that will cycle through the Mercedes’ logo until the power button is pressed, then once turned on says “system (or device can’t remember exactly) unavailable” and then turns off again. Probably one of the modules mentioned in the video? 2005 S430 for reference, thanks!
One of the components in the trunk is not working. Such as Amplifier, CD Changer, Navigation drive or any other components with the Fiber Optic jack.
In that box is a small fan that stays on when my doors are locked and car is sleeping. Thats why my battery is very weak.. also navi is not working.. 320cdi '07.. where i can find new one?
I changed the car navigation from the back and even the audio gateway which were used on another w211, and i still got the same problem, it turns on and off, could be the voice module or the taillight module?
You should bypass the Vice Module and find out. Tail light module has nothing to do with your sound system.
Hello. My radio occasionally works, but more often lately it doesn't work at all .No logo and CD changer doesn't come out either. Does that mean the radio head has a loose connection or needs replacing. Thanks
if there is no logo at all most likely the radio in the dash board is bad and it needs to be replaced or repaired.
@@HiTechElectronic but the cd changer will not open either, is the changer powered off the command radio?
@@RobThwaite Once the fiber optic gets interrupted, CD Changer won't do anything.
I have a feeling it is the cd player on mine when I turn the ignition on I can hear the CD player trying to select a disc and it seems to be trying all the 6 slots, hopefully I will sort it out over the weekend.
You could bypass the CD Changer and find out.
@@bijandaneshmand3659 hi I have done that, some months back I noticed the radio would come on in the morning after the car has been parked up over night then if the car was driven locally then park up the drive again and park up then drive again the radio would not come on at all until it had been parked up for several hours,but now the radio does not come on at all ,sometimes it will show the logo then go of,it's so frustrating, do you have any other ideas. Regards pete
Okay i did it got my sound and radio back. I bipassed all componets it was voice module. I still have sos error but command unit and cd changer sound work
Great video I have a 07 R320 which radio freezes. I have sound but radio will not change station, can't change any function but does have volume volume control freezes as well. Any advise what to check? I have a code audio gateway D241 cd/dvd cant be ejected.
Sound like you have a bad command unit.
@@HiTechElectronic I bought a unit on ebay and it did the same thing. Had sound but could not change stations and or change volume.
@@miguelortega7799 Does your car have steering wheel control for radio?
@@HiTechElectronic yes it does have radio control on steering wheel.

Hello, how are you? I had a problem with the battery, it drained quickly, so I took it to the Mercedes maintenance specialist, and something was separated in the trunk , and the problem disappeared, but the radio became stuck on the Mercedes logo. Do you expect the problem from the navigation unit?
If any unit with fiber optic connection in the trunk got disconnected, it could do that.
I have a ml350 and the system turns on the logo doesn’t go away non of the buttons work but the cd audio plays I just can’t use the nav/backup camera/radio what do you think the problem is?
I have a E350 2006 Benz and my battery keeps draining. We think we figured it out and believe that it’s the navigation system in the trunk and radio. But someone said I may have to look into taking the car to the dealership about the audio gateway for the radio. Any suggestions?
Most likely the Audio Gateway is faulty. Just remove the fuse for Audi Gateway and find out.
this probaly works but i tried following the steps but being that i didnt have the tools .. i juss disconneted both the main battery witch is in the rear and the conventional fuctions battery located in the front hood and put it back together my radio and navigation was operational again ...this is what i call a hard rest but it most certainly worked

Hi, I've got the same problem, but in the 2003 Mercedes E240
Hi there, I purchased a GL450 2009 and the cd player took the 6 cd's with no problem, but, after a family trip it didn't eject them, so, I took the command control out trying to fix it, couldn't do anything since is too complicated for my electronic knowledge, so, I put it back, hook up all the connections exactly like they were before, but, now it doesn't turn on at all,, can you please advisement? Thanks in advance
How do you bypass the teleaid module when the fiber optic loop is different from the other ones? What fiber optic loop do I need for the teleaid for a 2008 e350 Mercedes.
Here is the link for fiber optic loop: hitechserv.com/parts/
@@HiTechElectronic thank you so much I will definitely try this because the other two didn’t work. Thank you again.
@@HiTechElectronic
So this fiber optic will connect and work for the tele aid module for a 2008 e350?

great video nice one son, i have no sound in my 2004/5 clk320 A209, could it be the audio gateway?
CLK320 2004 does not have Gateway. Most likely the problem could be a bad amplifier or CD Changer. You are welcome to send both of them in for a free evaluation.
@@HiTechElectronic I am in the UK, any suggestions welcome.
@@douglasgower3266 Bypass the CD Changer first, If you still have no audio, then Amp should be bad.

I have e320cdi 2004 model. It has identical COMAND as in this video. Only when driving around it stops music or phone with an electrical beep for a few seconds then comes back on. Drives me crazy. Anyone have the same problem?
Yes, ive been dealing with this problem for over 2 years now. Its a high pitched beep and sometimes it doesnt beep but cuts out for like 2 seconds. Mine does it close to every one minute. Im geussing it has something to do with teleaid trying to send my location out and it failing but thats just a geuss. I have a 2006 e350 with the same type of command unit. Have you found out what the issue was?
@@RyLokey Hi thanks for the reply.
I never took the car to be fixed. Just lived with the same problem for over 6 years. Then suddenly last year about April it stopped and has never given me a problem again! I don't know what fixed it.
@@MrOogats Haha thanks for giving me hope! I notice it less frequently now, but maybe its because im used to it. Although whenever im driving someone who hasnt rode in my car before i notice it a lot more haha. Im hoping it goes away like yours did. I appreciate the reply!
In my E350 the radio plays but cuts off and on about every minute, did you figure out what the problem was?
@@Geodickerson Unfortunately I never did. I just put up with it for 9 years! Then one day it just started playing ok and never broke down for almost 2 years until 10 month ago it stopped altogether.
Very good presentation! I have a problem with the CD changer - sometimes it works well and then just stops and shows a message that says 'Error CDx" where x is 1 up t0 6. what can the problem be?
The CD changer mechanism needs to be replaced or repaired.
I have a 2012 cls550 rear doors and deck plays lower than front..before it wasnt doing that do you know can cause that everything else works fine what module can that be
Could be due to faulty amplifier.
What do you suggest replacing if all audio works but is distorted? also navi comes on but does not function. disc is in.
Most likely Audio gateway module is bad.
What fuses on the side is it i don’t know which ones is it
I own a 2005 Mercedes C320 4matic, I don’t have sound I check all fuses and all are in good condition,, but where I can found the amplifier? Thanks for your help..
I
If the car had an amplifier, it would have been located in the trunk, driver side.
@@HiTechElectronic thanks for the information…
Thank you. The video is very helpful. I have a 2007 ML350 with Harmon Kardon upgraded sound system. When I turn on the care, everything works, but after a minute or two the sound cuts off. I have tried replacing the Amp and the Audio Gateway under the seat with used ones I found I found on eBay, but the issue could not be fixed and I have tested the Command unit and that is fine as well. I did not however use a scanner to reset things after the installation of these components. Do I need to do that before these parts start working or could the issue be something else I am missing. Thank you in advance for your response.
Check to see if the car is equipped with a satellite tuner module, if it does have one, bypass it and hopefully it would fix the issue.
hey i have the same exact problem, did you fix it?
Me too i got 2004 e320 4matic with harmon system. I replaysed voice m9dule and cd changer sound is back bit always i got this module nect to tele aid on right side what is it cant find what it is looks like amp idk.

Also I'd like to know where I can get the cable terminal , ( what side of the vehicle) I saw like a double connection in the left back close the the fuses.
thank you !

hey, i have a 2007 ml350 and when i turn the car on, the audio works then it cuts off after two minutes. I used the bypass loop for the amplifier and tele module checked the fuses but it still doesnt work.
Greetings… thanks for the informative video. In my case nothing comes on at all. Fuse is ok so what else should I check?
Hey guys, I've had a 2008 Mercedes Benz E350 for 2 years now. The Harmon kardon Logic7 sounded amazing. Until one day my CD changer stopped working while I had CDs inside . I've been reading forums and some people said to remove the fuse for AGW, the CD changer and the radio. I followed the steps took the fuses out, put them back, and at the end the CD changer started working again. But ever since I removed the fuses and put them back into place, my sound has not been the same. I used to get powerful bass from the front speakers, and the subwoofer , and an awesome clear surround sound experience. So much question is do I have to go into engineering mode to get the sound back, or what do I have to do to get the sound? Because I believe that after removing the fuses I must've messed up a component in the radio system that has to be readjusted. I still get sound, but it's not the same as it used to be before I removed the fuses. Sometimes I try, and I put the bass to maximum, and nothing happens.
Guys please help me.

Your navigation drive unit in the trunk needs to be replaced or repaired.
I have a 2005 E500, after a dead battety and some moisture in the trunk. My radio stays on but no sound. It's stuck on the logo. It does not turn off. I checked all fuses and tried re-setting but no luck. You have any idea what could be the issue? The radio/nav worked fine before the battery went dead.

Hello, my comand unit NTG1 does not start when i push the Power button. Sometimes it does, but most times not. Most times, I would pull out FUSE 26 from the Radio Unit, and it would start. Now, even if I do that, it still wont start. I have bypassed the Navigation unit and the Tele-aid in the trunk, and still does not start. I suspected the AGW but after seeing your video, and listening, I think for sure it's the comand unit. PS: I don't have CD changer. Any sugestions?
If there is no Mercedes Logo when you power up the command unit then the command unit needs to be repaired or replaced..

My 2002 s430 radio display is not working. The radio and all the functions work fine but no display. I can listen to the radio and changes station but the display is black. Any suggestions?
Either the LCD is bad or the circuit board behind it. You need to have your radio replaced or repaired.
Ok so I narrowed it down. I think it’s my Audio gateway I checked all the other audio components with the fiber optic. Smh and the radio still doesn’t work but I keep getting static and then the radio just shuts off. I also found out my left taillight has been getting rain on so I believe the rain has messed the audio gateway up so no radio until I get that fixed, by any chance do you know how much it will cost to get a audio gateway installed for a 2008 e350?
