this problem has happened twice in the past week. After starting the truck, the display for the clock/radio does not come on, nor does the radio. Repeated cycling of the ignition switch on and off has no effect. Driving down the road, it magically begins to play, but the time is not correct. Time does not reflect a loss of power, nor do I lose the presets. Noise from the speakers sounded like you were twisting the tuner knob on the pre-electronic tuning models, and then went dead. Any body have this problem? I hate being without the tunes!!!
