How To Use Optical Loop To Isolate Broken MMI Devices

www.dognmonkey....

[@markstone7142]

A great workaround - nothing worked from the MMI down. I ordered a "Most Fiber Optic Loop Cable Bypass Female Adapter Detection Ring Cable" from Amazon, undid the fibre connector from the K-BOX RADIO / STEREO TUNER in the back RH fuse area and installed the fibre loop to the male input - bingo... MMI and most functions came back to life. No radio, but that's what is broken and left the fibre circuit open. I'll deal with the radio issue next, but everything else is working again. I'm very grateful that I was able to bypass with the fibre loop - many thanks for the vid and how this can be applied to other devices in the Q7. A really cheap and quick fix. Best regards all the way for Australia :)

Is there a video about switching from mmi 2g low to 2g high or even 3g with all necessary constraints?
I am struggling to find in on the web.
I have a6 2006 C6 4F 3.0 tdi with monochrome 2g low, and would like to dive into this upgrade.

Edouard Fleurant yes, the optical loop is opened again, check all the power and components with MOST bus. Check the fuses in the trunk, 5A on the left and also big fuses behind the battery. Go to my website and search for black screen

Edouard Fleurant the exact same thing happens to me when using a BT transmitter... did you ever get the problem resolved?? And where you ever able to use the transmitter
