Hi All,

Have just recently bought a 2008 A4 with MMI.

I have tried to connect a tune2air bluetooth adaptor to the AMI port in the glovebox, but it does not recognise it. It appears the adaptor does not even power up.

I measured voltages on the AMI power pins with MMI on (should be 5V USB between pins 25 and 28) but it appears completely dead.

Is there a possibility the AMI is disabled or only powers up under certain conditions or should it always power up to charge devices etc? If not should I suspect it is disconnected.

Any ideas where to look?

Thanks

Mike
