Nice information!

My AMP finally blew tonight.... Well at least I think it has, my idrive has been playing up intermittently every now and then for a month or so.

Tonight I got in the car and there is music playing but only for a second, then stops for a second then plays for a second etc... at very low volume and crackly. music only come out the front door speakers.

The idrive keeps reverting back to the radio menu, the TV functions dont work it wont select a channel, I can select ipod tracks with a few attempts but they wont play unless you keep trying! and the ASK wont play CD's! Also the MMI wont shut off after I have removed they key!

INPA cannot communicate with the AMP so im assuming thats the issue? It sounds more serious than just the capacitors or amplifier IC's going down and more like the actual MOST interface itself is rebooting. Or could the AMP be rebooting as one of the caps are short and its PSU is overloading and trying to restart?

Will pull it out and loop the MOST bus and see if it is indeed the problem!
