I have had my x920bt installed in 2 different cars with the same issue. After 30-40 minutes of driving
with my iphone connected to the cable and listening to Pandora or my ipod, the stereo looses communication
with the iphone. It will not reconnect until the car has sat for a while, which leads me to believe it is a
heat issue. It will still stream via bluetooth and the sound still works, but the phone won't connect via
the cable. I have tried two different iphones with different firmware versions with no change. I have also
tried to duplicate the problem with just power and ground connec
