Once I recieved my 2008 E70 with factory iPod, I went out and got a new iPod Classic 6th gen. The iDrive recognizes the ipod and I have full control over it and can play songs, but when the car is shut down the ipod stays powered and eventully goes dead. The iPod never charges thru the cable either. If I unplug it from the vehicle, it remains on the "Device attached" screen and must be reset. I returned the ipod to apple and got a new one that does the same thing, so it must be the truck! Anyone else having this problem?
