Yet more questions about MMI and AMI Versions

[Scotty1]

Well I took the advice above and went for 5570.

Plugged in the charger,
Removed and CD's
Made sure my phone (BT) was miles away etc.

Disk one went well and as expected.
Disk two went well and as expected I had to do it twice.
Disk three went well.

Happy me...no...seems the jump from 900 to 5570 is too great and now the BOSE is in Component Protected (CP) mode, so I only get sound through front left speaker.

I have the Ross-Tech cable etc but as those in the know will tell you, this won't fix devices in CP mode.

So trip to Audi planned for Wednesday.
