I am a first time BMW owner with a 2010 X5. I've had it a few weeks and it's equiped with the ipod/usb y-cable adaptor/connector. I've been using my new-ish ipod nano with it and while it is compatible, the idrive system randomly drops communication with the nano even when it is in the middle of playing a song and then the screen says nothing is connected. I have to remove and reconnect the y-cable to the usb plug before it will recognize the nano again - unplugging and replugging just the nano to the connector does nothing. I've noticed it is more likely to happen after I've placed or taken calls thru bluetooth or jumped around on the radio or thru my nano using idrive. Has anyone else experienced this?

I am taking the car in for service next week, but I am concerned they will not be able to replicate the problem since it happens so randomly. I don't want to go in and have them tell me they couldn't see the problem and then do nothing. I thought maybe I should ask for a new y-cable but could it be the wiring from the usb to idrive? Thanks for any help.
