Hi,

We just tried to upgrade the existing MMi 3G High on the car of a friend (Audi Q5) to MMi 3GP.

So we change existing stuffs by these ones:

Head unit 8R1 035 666
MMi Console 8T0 919 611 C

Everything was working but we lastly try to update the firmware to 8R0 906 961 DH (K0767) and now no more sound in the car.What could the the problem??

Here is the screen we get:



Thanks in advance for your support
