Hi

I started installing my advanced aps system and the backup camera that i purchased from kufatec a few months back. I am not done with the install. I still have to connect 2 cables to the can bus, and drill the holes on the front bumper for the sensors.

This afternoon, checking the radio making sure that everything works before rebuilding the rear of the q7.

at first it worked fine but I now had a TV section (no Image) in the mmi that I did not have before. it took me a while before I could get back to my regular media screen to access my dension and cd changer.

then the MMI crashed. I am not sure why but it just froze for like 30 seconds and i finlly turned it off. When I turned it on, its like it lost all of its settings, as if its a newly installed mmi without any settings. It even has air suspension display, and I do not have air suspension.

The Problem: My system is on a complete mute. I cannot unmute it. I have tried reseting with the three buttons, but still nothing.

Any Ideas?

Do you have a VAG-COM? have you scanned your car for fault codes?

with the vag com, I put everything back to normal. My front sensors are completly installed and work perfectly.

the video controller the i had to buy with the camera was the issue and am not sure how to fix that.

There are also 2 cables that have to be connect to the CAN bus 0ne on 14low the other on 14high, but there are already 2 cables in that spot. So I am not sure if I can remove the original one and work from there or if i can put them in another spot of the harness.

I am also thinking of updating my MMI. I got a hold of the 5150 and am not sure how to go by doing the upgrade. Also Do i upgrade after all the mods, or before installing the camera.

Thanks
