my communication system(the display and functions of the nav, radio, phone etc.) is randomly and completely shutting down (blank screen that flashes occasionally, but no functions). after it sat for a while and i restarted the car it would begin to function again. seemingly there is no correlation between any starting, stopping or time related events.

the dealer suggested that the problem was my blackberry curve phone. after turning off the blue tooth function on my phone the system worked fine for about 10 days and then it failed again.

has anyone else had this issue and resolution, please.
