I bought a very nice A6 3.2 Quattro from 2005
but
I want to update the MMI and both the factory fitted cd changer as the MP3 cd changer dont work correctly, so I am stuck..
If I press "setup" and "return", the current config sees them both.. and gives my lots of info like version, manuf. date etc
I can load cd's in both of them but when I click the cd/tv button on my MMI it doesnt see anything. It doesnt even display the slots. As if they are not there or not hooked up, but they are (at least I think)
Unfortunately I dont have VAG-COM (yet) so I cannot investigate further, the dealer is busy the next 6 weeks and that is a long time to wait..
Any ideas?
Could this be a "component protection" problem?

I read something about that subject
