I have a question about the 3GP retrofit again. I have been in 7 times to try to fix the CP, but the dealer isn't able to remove it. And I still have no sound. The Nav and telephone audio works fine. I even got an original Bose for C6 instead of the C7, but still nothing.
However, today something happened. I did my usual checks and I opened the amp with VCDS and pressed actuator test, and after hearing sound from one speaker, I canceled the test. And then suddenly the audio started working! The joy was short lived. When I turn off the ignition, it's back to not working. If I repeat the procedure it works again until I turn off the ignition again.
What could be the reason for this? Is there any way to get permanent sound?
And as a sidenote, when I get the sound working I loose the Navigation.
"Navigation data are not enabled" is the message that comes up. If I restart the MMI it's back, but as soon as I get the sound, the Nav dissappear again.
It's very strange and it makes me think that there must be something wrong with the software?
Everything else with the MMI works fine, except not being able to remove CP and the missing sound.
