I just got my X3 few days ago from the dealer. It came with the y-cable (I dont have tech package or nav or mobile office). When I attach an iphone 4 or an ipod, x3's idrive recognizes the device and starts the playback. However after 30 seconds to a minute (this duration seems random) idrive loses connection shows no usb connected. Waiting more the system re-recognizes the device just to loose the again.
Has anybody seen this happen? Did the dealer gave me a wrong Y-cable (I dont know if there are different versions), or am doing something wrong?
