How to troubleshoot sound and navigation / fiber optic / MOST Bus System of 2002 to 2008 BMW 7 series 745 750 / E65 E66 for repair.
I cannot thank you enough for this video. You have saved me $1764.37 from the dealership's prices. Instead of doing this troubleshooting, they said I needed an entire audio system. I purchased a fiber optic loop from the dealership and the culprit was the Satellite Radio module. I plugged in the loop and now I have audio in all components and the SOS System now works.
I have a 2007 550i and the procedures works the same. I recommend changing the title to BMW Fiber Optic Troubleshoot, that would increase your views by 20k. I stumbled upon your video through youtube suggestions.
Thank you for this video and be blessed.
Corey Bryant I have the same problem my 550i 😣😣😏
My 2008 bmw 750li had audio issues and now it is working. Thanks so much for this video. It has definitely saved me so much money!!!
Thank u so much I ordered the loop after 3 weeks of silence in my car now it's back
What was causing the problem in yours?
@@daygowest9346 *_Probably the radio module was dead. So people are ordering a wire to loop the system. Apparently it works but I will try it tmr on my gfs grandfathers BMW. His is also shot, so I want to see if it works._*
I started to have issues with my subwoofers and started to dig on how to repair it. Long story short, I added an EQ and a couple of amps to my 2003 745Li and now all of my sound system is independent from that garbage Logic 7 BMW put in these cars. I can finally play music off of my iPhone or any other MP3 player...and LOUD!!! :)
Please Tell me how you did it....I need ur help!!!
how much did that run yu $$
Just recieved the fiber optic cable, thx for the quick sending, thanks to you everything works fine again
Can I get it in Nigeria
@@segunfamaye5377 bro you have 7er in Nigeria ?💀
@@davidschober49 😂😂😂😂
Best video out there. Just watch it a few times you will understand how it works.
Muchas gracias amigo mañana mismo veré todos esos detalles en mi 750li 🎉
thank you for this video and all the others, you are the best............
Be great to have a link to remove the carpeted cover on the trunk units

The ask unit with the FM/am buttons does this have a built in tuner
truly helpful.....2006 e66 750liI had no radio, cd player, satnav, clock, tv, or sounds of any kind.I bought a fibre optic loop and started in the boot (trunk for you Am's) nav disc player first, -no change.the big one next (don't know what it is) -no change.logic-7 thing next, BINGO! I pulled the plug and inserted the loop then went back in the car and the radio is on!I have sound from all speakers although it sounds quite dull....also,satnav, tv, radio stations, cd player, information sounds and chimes- it's all there.so now I know which component is at fault and I feel quite triumphant so far as I feel a bmw tech would have cost me a bundle so far.....now to look for an answer about the logic-7 box/thing/amplifer whatever it is lol.many thanks so far...........
+Matthew Kingham please ignore the lines through my text.......
where did you buy the bypass loop from if you dont mind me askin
+smooth gaskin "audi a8 fibre optic loop diagnostic connector" from amazon.when you get it, break open the plastic "lollipop" shaped frame and remove the loop.......you end up literally with a small piece of f/o cable with a small plug at each end.what are you working on?
+Matthew Kingham 2009 audi a8L
+smooth gaskin nice. good luck!
I got a 08 750 li no sound or radio station or number i think it might radio unit or the Amp I learned alot in your video
I enjoy your knowledge on the audio system on BMWs.....I have a 06 750LI and my subwoofers under my front seats sound muffled and distorted!....Is it my Logic 7 amplifier or the subwoofers have gone bad??...If I use my lollipop on the Logic 7 and the subwoofer sound good, does that mean my Logic 7 is bad??....Pls. advise me on this issue....thanks....AMM
Most likely the problem is the Logic-7 amplifier not the subwoofers. FYI if you bypass the amplifier your subwoofer wont have sound anymore!
thank you, the official repair reclaimed 4000$ for this problem, they would change everything in new😰
Thanks for that detailed helpful video. I have a 2004 e65 and I started having the display freeze from time to time and not have the radio or anything working. Recently there has been a hissing sound in all the speakers. I used the balance and fade and heard the hissing sound in the front and back. The radio and cd player work but it has the hissing sound always. I disconnected the loop in the glove compartment for a min and reconnected but still hissing. Could it be the amp?
caleb essel The loop connector in the glove box has to be connected at all time. You need to get an extra one to check your fiber optic lines.
No sound at all .The other light are on but my loop connector in the glove compartment light doesnt come on. Would the fiber loop still help ?
Hi. Great video. I have a problem with my 2007 750i. I noticed while troubleshooting that all of the modules have a red light going through the fiber all the time, but the amp does not. Should the amp always have the light on like the other modules? Maybe I have a broken fiber? Where is the loop initiated from for the amp? Could a bad receiver cause the fiber not to light to the amp? Any help is appreciated.
I know it been years since u posted this video. But is it possible to not have the Fiber optic wires at the Navigation unit in the trunk? Mine don’t have the optic wire with the harness on the navigation unit.
All my speakers are working except subs and door gonna try fiber optic loop hope it works..
Hi there! Very good video! It helped me a lot! Cheers!
Your video is well done and very helpful. Our 2004 745i Motorola Bluetooth appears to work but when we attempt to pair with our iPhones the pairing screen comes up and disappears.
+Steve Siegwalt Unplug the battery in the car for 5 min to reset the bluetooth module and try again. If it is still the same then most likely the bluetooth module is bad.
+HiTechElectronic thank you I'll give that a try!
Hi I have a 2006 750i, when I listen to the radio only the driver side of the audio works... when I balance to the passenger side only, I can only hear crackling. What do you recommend me doing?
What was the solution dude?I have the same problem in an03 745li
Very helpful video. Question: I have a 2002 740 iL with a MK3 nav unit and non lighting radio screen. It flashes every few minutes. The faceplate tilts to insert a cassette. The display stays blank but the cassette, multi cd player and radio all play for about 2 minutes then stop. Turning the power on and off it will play for another 2 minutes. If I bypass the MK3 and that is the problem, will the audio display work again? Also, if so, can I leave it bypassed? (dont need the ancient gps) Thanks
I need you to make a quick video on how to get to the modules in the trunk and how to properly take out the radio
I have a 2007 650i. I'm trying to troubleshoot the audio equipment. If The CD Changer is missing will it need to be bypassed? Also what is the part number on the MOST loop you are using in the video. Thanks
Phil McLeod Yes, it needs to be bypassed. The plug that we use is a modified one.
HiTechElectronic Do you sell this plug? If not how do you modify it? I have a MOST LOOP but the bottom of it is female. The bottom of yours is male with what looks like opening in the end to go over the two leads of the optical connector. Thanks
Phil McLeod Yes, we do. Please call 818-785-8085 to place an order.
Hi There ! Share my efforts. Fell into the trap BEFORE i understood how its all connected, Like Xmas lites 1 buld goes out whole string goes out .. I bought Typical Logic 7 amp ... used ,,, still not all speakers work ...... Waiting now for Used ASK unit... ( for 04 e65 745) As my car is that ... Never twigged on ASK unit rubber volume / off on button just was wiggly . n just spin NO clicking . Wait n see Everything wit the radio was good , disply etc JUST sound from only 1 door speaker Great video!!!!! BTW
I sent the Navigation Unit via a BMW dealer in for repairs and i was told they could not find a fault, than the BMW agent told me they checked all the wiring and also could not find fault than they told me they found a fault on the monitor and repaired but i am still having same issue with only the nav part of the monitor not displaying clear. Now BMW has finally decided to replace the unit. when i spoke to them today they informed that the parts they will replace is what they describe as (80 Control Display) and (Monitor). Does that sound right as i got a price from another dealer and only for the unit in the trunk. i am confused and don"t think these guys know what they doing. I am now battling with this problem for 5 months, although they are prepared to replace the components at their cost why do they want to replace two components, whereas the other dealer gave me a price on only one. Thank You once again for your kind assistance. Bobby (South Africa) 2008 BMW 750i
so i just need the optic fiber bypass module loop? then just "bypass" everything? then ill be fix or will that "lollipop" tell me which one to replace?
It will tell you which one is bad and if you are not using that module then you could leave it bypassed for ever.
Do i got to leave the loop there on all the connectors? or do I put it on there start the car then plug the connector back into the module?
Hi there, how much do you guys charge to repair the cd changer? The cd cartridge in the cd changer in my 2007 BMW 750Li is stuck and will not eject. I'm considering fixing it maybe vs buying a used one off Ebay. Kind regards - Alex.
Please check our website for prices. Ebay used items are cheaper to buy.
@@HiTechElectronicwhat is the differences between the ask units one have mode fm/am buttons the other dont
So I put a lollipop on the logic 7 amplifier even tho cds would play and the radio it would just cut in and out so I put one on it and it stopped it cutting in and out. But my question is how do I service my 745i 2003 e65. I’m hoping when I register my battery it will fix my trifecta light bc it’s so annoying seeing it
I get it now.. I need to order that fiber optic loop...
Here is the link to purchase one: hitechserv.com/parts/
This is a great video! I has no idea how to troubleshoot the problems I'm having with 07' 750Li. I'm going to try this over the weekend. Question, if I figure out which module is giving me the problem does that mean I need to replace it? Or have it refurbished for that matter? Any advice would be great. thanks. .
+Jared Gray Some of the modules you can leave it bypassed but some you have to have it replaced or repaired.
@@HiTechElectronic I am checking a 745i bmw no sound from the radio CD CDC works but the CD unit have the am/fm mode button the other only have seek/scan button the unit with with the am/fm button it shows all the stations but no sound the other unit I think is the original because the trim plate fits it but not the other unit...?does the ask unit with the am/fm buttons does radio audio supposed to work.
@@HiTechElectronic more hi calories? 😂
Hi, great video. Ive bypassed every optic module my e65 has but couldn't get it to work again, would this most likely point to either the idrive unit itself or the ask unit? Because they cant be bypassed? Do these 2 units need programming to the car? Thanks
zeus200044 Most likely the ASK unit.
+HiTechElectronic 750i sound not working no bass navigation n CD dnt play the CDs. what can I do
I have no sound and no numbers next to the radio stations which item should i send you to repair? how many items can i loop at one time ?
Jorge Fernandez You need to figure it out yourself since you have the car with you. You can loop as many as you want but it requires lots of bypass connectors !
I recently installed 2 new speakers to my rear doors because i realized that there are no speakers in there, but there is no audio coming out of it? my front doors speaker and rear deck speakers works except my rear doors speakers?
Do I need more then one bypass cable .. I tested all with one but not enough cable to test more then one at a time ????
If you have more than one faulty components then you would need more bypass otherwise one is enough. Having more than one bypass connectors make it easier to troubleshoot, sometimes we use 3 or 4 of them at the same time.
@@HiTechElectronic thanks ordering them now im going to order 4 of them
Hey I tried everything you said on this video with the lollipop and it’s still the same. Only thing I haven’t tried was the radio it self cause I don’t have another radio to test it out. Once a month the front speakers would work for an hour or so then nothing sometimes the display freezes.
How much do you charge to repair ask unit ?
Please check our website for prices www.hitechserv.com or call 818-785-8085
Hello HiTechElectronic. I just purchased a 2006 BMW 750 Li from a co-workers friend. He said his CD player wasn't working because he had previously installed an aftermarket CD player and didn't know how to connect the factory unit. After some further reviewing of the car, I noticed the navigation doesn't work, nor the clock, door chimes and neither do the vehicle settings to let me know if anything needs to be serviced. Do you think I should take it to a stereo shop first or should I try the series of bypass loop? Thank You
+Bernie Rocha You need to install the original unit back in the car and then check the complete system.
Thank you friend.
Hi there,
I've been having some problems with my BMW E65 745i 2002, the radio is not working but the CD works fine. I can also see all the radio stations and find new ones, but I'm not getting any sound from the radio, but get a great sound from the CD.
What could it be?
+Boddi “Bugout” Jonson It could be a bad Tuner module or ASK unit.You are welcome to send both of them for a free bench test.
Hi I have the 2007 BMW 750i and my NAVIGATION isn't working, also the audio system is very bad . I can only see the names on the screen like FM,AM ,AUX but not stations available. After I have watched your video ,I believe the NAVIGATION unit cause the problem. Please comment below your opinion. Thx
Please watch "Part 2" video as well. Any unit with fiber optic output could cause this issue.
When u ship how long does it take to receive it
@@viktorthomas2668 3 days.
So I found a schematic. It seems the signal for the input for the amp should come from the FM receiver. Do you guys repair that component as well?
+Vivian Bracey Yes, we do.
Good day!! Where can I purchase the Fiber loop cable for Bmw 750!
My problem is only the front passenger speaker works properly. All other speakers are not working ! What I suposse to do in this occation?
Most likely the amplifier is faulty. Here is the link to purchase the Loop: hitechserv.com/parts/
do u repair only or sell already repaired amps and mask units. also is yiur repair fix the factory flaws that cause the amps to burn out so quickly or is it factory spec. I am alps trying to find the fiber optic loop on yiur site and I cannot.
If the logic 7 has no bass at all from subwoofers I took the amp out unpluged the second small plug not the long one it got them to work but for 5 min then we shut the car off and turned it on they started workung at least 10 and went off iff I unplug the long one will it due any good and theres a white plug not attched to any thing is that supposed to be like that and
will a bad LVDS cable between the m-ask and screen , cause them both to not operate.
Can you please tell me if I would replace the communication module of my 2005 facelift with an 2007 e65 communication which it has the PK on it, it might work without inserting the module in the system? My issue is that when I am trying to connect my phone to car by bluetooth it asks me for that 4 digits pin which I don't know how to find them since are not written on the communication module.
So I used a optical loop for my mmi radio and it work for about a month but now it cut back off, and won’t come back on I bought another loop and it still doesn’t work, what’s my next option
Keep bypassing rest of the components to find the faulty one. If all are ok, you need to have your ASK unit checked out.
Thank you so much.
Hi, i have 2003 bmw 735i, on screen says please insert the cad, what’s the card ,??
Fm is working,CD working ,but the rest system not working,please help,
did u take the loop apart or did yours come like that please advise..because my loops looks like yours but is completly covered
The loop separates from its plug housing
Hi.. Nice video.. my CD changer is not working, it makes a clicking noise when it tries to load the CDs at start up.. I observed it, and basically it gets stuck trying to load the CDs.. any recommendations on how to fix? thanks
I have the same exact issue!!!
i changed the CD changer itself, and yes by myself. I don't recommend it unless you know how to disassemble and enable electronic cable connectors from the board. I'm a Mac Genius, and it was still challenging because I've never seen that type of connector. But anyway, next I will test a new magazine.
I just called you guys today about my CD player on a 2006 BMW 750li. The Radio, Navigation, and Phone are working fine. The CD player has no sound. I carried unit to a local shop and they informed me that I needed a refurbished unit because sound wires are corroded, Before I take that route is there possible another fix.
What is the name of this cable?
Wow u are the man I will call you tomorrow thank you so much
Hi, I recently baypassed my Telephone Control unit because it wasn't working, but after I baypassed it, when ever I play a CD it switch off to FM, it's like rest the monitor every few and then. Do I need to buy a new Telephone Control unit, because maybe some things can't be baypassed.
Telephone control unit has nothing to do with the CD player. There is an issue with your CD player.
HiTechElectronic but I changed my cd player, and still the same, when I play a song from a CD is suddenly stops and switch to the radio, could there be another faulty unit?
The CD player must have been a used one or the disc is faulty.
HiTechElectronic this still the same, the CD player I took was from my friends car which was working perfectly on his bmw. Sorry maybe I didn't use the correct words to describe my problem. Every time I play the CD it gets interrupted, this happen even when I'm playing the radio, it's like the screen keeps resting?
Bypass one by one all the components in the trunk and test your cd player and radio to see if the problem is solved.
J'ai un problème, mon radio ne fonctionne pas, ou je peux recevoir se câble ?
I had craking noise, and so I repaired the ask unit, and that fixed the issue but no bass so im assuming by logic 7 is bad. I don't want to fix it as itll go bad again can I just add external amp wired to the logic 7?
My car is doing the same thing i believe. Music will play for 3 seconds then crackle music will play again for 3 seconds then crackle. How did you fix this issue?
I have 2007 bmw 750li and I bypass the satellite tuner under the truck and the radio works but I have a noise coming from the driver door speaker. How much to repair the satellite tuner and what’s the next step to fix that noise from driver front speaker
Whats the web page so i could send the stereo to get fix?
Just ordered an ask unit from ebay. The ask unit controls the whole audio system?
good day....what does ETC means on my front mirror? What is the card slot behind the mirror stand for?
I have a 2002 745i and my idrive knob stopped working but everything else was still working until last night. Not only do I not have any sound but nothing comes on. Is this a battery issue or fiber optic loop issue?
+Andre Bishop If your display is black then you need to check your fuse first.
HiTechElectronic
I need help on my ASK unit......When I play my CD player it will not memorize the last track I played.....It continues to go back to CD 1....When I turn the car off....it will go back to CD 1 rather than memorizing the last track I played!!...If I turn off the CD on track 7....even if it is only 5 minutes....it will go back to CD 1....the beginning....It will not memorize the last played CD/Track I left off at??...Do you know if there is any option or adjustment to remedy this issue??...Please HELP ME!!!...AMM
hi I have a 745i with several problems, fm channels very weak and no audio warnings, pdc or sat nav voice. could it still be the ask as ive replaced all 3 big capacitors inside it for the no audio. also the fm channels weak, will it be the fm amplifier or fm amplifier diversity ? thanks
hello is the fiber optic works on 330d E46 please? because i have this problem on it. thanks
Same problem here, it's a 2013 X3, I bypass the SOS module, nothing, then I connected a new amp, no sound. The radio works fine, what else can be?
BMW X3 has totally different sound system. If all the functions work fine including navigation and 12v power to the amplifier. Then you might have problem with programming of your CIC unit (radio/CD player} in the dashboard.
@@HiTechElectronic thank you, I have the cable and need to contact somebody to help me with the coding.
@@ABWSKITCHEN once you do that, check to see if the CIC unit is reset itself back to default "internal Amp" or the coding is correct, should be "external Amp".
@@HiTechElectronic thank you so much, I will try once I fix my laptop.
hey the radio on a 2002 750i doesnt work. would that mean i need to swap the tuner module?
Which one of the fiber optic do I need ?I have 2002 BMW 745li
I need one two
Hi ... I have a problem with the sound of my car. The car is a BMW e60 545i. There is logic 7, but the front door speakers do not play. I tried 2 amps nothing happens. The problem is the same. Could the problem be in the cd player ????
Yes, the problem is the single CD player in the dash board.
I've determined the subwoofers are both good. I've taken out the amp. How much do you charge to fix the logic 7 amp with bad subchannel? What is the turn around time?
Thank you
Please check our web site www.hitechserv.com .
Is this a male or a female adapter?
I want to purchase one but seems likes the pictures show connectors rather as same as the input sockets on the car and it wont work/connect. While what you are using in the video has exposed connecters on the loop connecter.
Help needed
It is a male adapter.
What's the name of that jack you set up. THANK YOU
I have a 745i. I lost my radio channels and cd ,cdc options are grey. My lollipop in the glove box doesnt have any fibre optic light on. Voice module in trunk has light, navigation has light but not ejecting disc, communication module doesnt have fibre optic light either. What do you think it could be? Im @a lost rite now
Double check your connector in the glove box, if there is no fiber optic light then the problem could be the ASK unit.
Hello, i have looped all the units one by one ( cd changer, voice module, nav, telephone and even the fm/am module in the pillar ) and still nothing, what do you think the problem is ? i had the system frozen while i was driving when the music stopped, next day sound was on while reversing and i took the car for a longer ride and stopped again and since then iDrive frozen no radio and no telephone nor trip computer.
Thanks!
Then it must be a bad ASK unit.
70% of this is the amp which is notorious for going bad. I am on my 5th unit in 3 years of owning a 745.
NAAM COMM true all my speakers worked except the underseat subs went to junk yard got a new amp $12 and it worked !!!
NAAM COMM the bass in my speakers has gone out, is that my problem as well?
mike brooks replace the amp it worked for me
What if no red light is coming to any of the units in the trunk.
Does this thing come with a gas station?
Hi, I have a problem with my 735i 2002 BMW, the left side speakers have sound but the entire right side has no sound, also my car doesn't have the logic 7, so what the problem could be??
The ASK unit is faulty.
How do I troubleshoot a display screen that just show colored lines
I think this all relates to my issue. no sound from bluetooth. music through aux sounds distorted and no matter what source im using for music ask unit volume lowers or may even go off. is this related to these issues?
Did you ever it fix and how because I’m going thru same problem now as we speak with ‘07 750 to the point my whole screen blank out and my temperature gage frozen
hi i have the same problem with my bmw 730d 2006 i think its the communication module that controls everything sound fm cd navigation some people call it Bluetooth module if i put a second hand in do i need to reprogram it
hello i have exactly the same problem not signal bars of the navigation and no sound when i open the doors i dont know what to do im hoping that can be fixed
thanks
Hello I own a 2007 750Li and my radio is not working (FM has no channels), satellite radio has the same too, and my phone bluetooth doesn't work either. What is the most likely reason for this? A fuse or one of the components and how do I narrow it down? I appreciate any help you can give, thank you. Glen.
You need to follow the instructions on this video to find out.
Hey I got the same problem on my 2006 750i the CD player works I loads the cd but didn’t have any sound, I have no stations am/fm/sat, I tried connecting my lollipop/most bus to the Logic7, nav, sat, and still doesn’t do anything none of the steering wheel buttons and only thing that works is the climate control any tips?
I bypass all the components in the trunk and still no sound ?
This video is very informative except the fact that I buy the Fiber Optic Loop you mention and it did not fit my 2008 BMW750LI cause you forgot to mention that there is female/male loop. I waited 10 days for the loop and took me quiet awhile to dismantle the component, just to find to my dismay that the loop does not fit.
+Benson Reuben You should have bought it from our website.
+HiTechElectronic ......That's the first thing I did but upon searching for it on your website, the search came up empty. Perhaps instead of writing smart ass answers, you should update your website cause it looks like one from the 1990's !!!!
+Benson Reuben The new website is coming soon. Thx.
+HiTechElectronic so how do I get this loop from you that fits into the fiber optic loop and how much will it cost?
+Benson Reuben Please go to our website, in BMW category, look for "BMW 745 troubleshooting guide"
and click on "buy now" button. You can also send me the picture of the connector that you bought, you might be able to modify that one. Our email is in the website under "contact us".
I have BMW X5 2008. All of sudden I drive screen went dark and no audio. In the trunk there are components, phone module and amplifier. The amplifier don’t have a fiber line to check, only the phone component has a fiber line hook up. Pleas help
The problem is the CCC unit "Radio/CD/Navigation" in the dash board.
Thanks for the reply. I checked the fiber to the phone module, there is blinking red light. I checked the fiber line under the dash board, there is a blinking light. The amplifier has no fiber line connected to it. I don’t have navigation system or data LT radio. The speakers every once and a while they make a cracking noise. You mentioned the ccc unit is the suspect. Before l buy new one(very expensive) how do l make sure that the ccc is the problem. Thank you very much.
If your car does not have navigation option then you have have M-ASK unit "Radio/CD Player". BMW X5 sound system is not like BMW 7 series and if the display is black you do not need to check the fiber optic lines. You need to check the fuse for radio and display, and if all the fuses are good then the M-ASK unit needs to be replaced or repaired.
Thank you
What could be the problem if I bypass everything in the trunk but the radio functions still dont come on my screen still looks like yours does in the beginning of this video
Then the problem could be the ASK unit.
I have the same problem, If you bypass the navigation unit is everything else going to work back again? I allready tried another navigation unit from another e65 and then everything worked fine, but i don't use the navigation of the car, so can i just bypass it so i don't have to buy a new navigation unit?
+erzincano84 Yes, you can bypass it for good but use a zip-tie to keep it together with the plug so it won't come loose.
+HiTechElectronic can i order this from you? If yes do you send to belgiul?
+HiTechElectronic i mean belgium :-)
+erzincano84 Yes. Please go to our website and place your order under BMW.
Our website: www.HitechServ.com
+HiTechElectronic done, thx for the quick response
my car is the same problem, it has no audio does not have displey does not work the cd player when, the check had fallen oil to the module but the navigation did not enter only the INPUT VOICE COMMUNICATION MODULE UNIT
Will that be?
Daniel Jaimes i have the same problem with the oil. Help please!
Hi guys
Is there anyway how I can upgrade my radio,system,settings etc as some of the options doesn't work when I click on them. Can't find Bluetooth either.
And one more question. My radio can't find any stations only if I look manually. And when I'm stationary volume is all ok but when I'm on move than my volume goes up and down,constantly till I don't stop and than when I move it goes up and down again.
Can I reset it or something?.
Thank you
I have a 2002 745li, the driverside rear deck speaker is the only one that works. The prevoius oqner had an after market system in the vehicle. I reconnected the wires the the L7 and i still have the same isssue. Radio am and fm works/cd player works cd changer works everything else works . I basically have only 1 speaker. What do i next?
Most likely the ASK unit is bad.
Hello, are there any companies in the bay area that can perform this repair. Please contact me if so. I need to get mine fixed.
in my 745i everything works fine, but the car doesn't remember witch audio source was on when i drove the car. So i listen to cdc, go out of the car and lock it. then the next day i open the car and there is no audio. i have to manualy select cdc or an other source to have audio again. any thoughts? maybe coding? (i can code with nsc exp)
+Yester Dailey It is not coding and it is not a common problem. Sounds like a bad ASK unit.
+HiTechElectronic thx, i changed the ask, but no difference. But, with my other key (key2) is works fine! so i think its car/key memory setting?
Everything works on my 750li 2006 but there’s a really low audio can’t seem to find the problem
Bypass the amplifier in the trunk and try it again.
