So I read all the info about pulling jumpers and resetting system for audio problems, usually when the audio won't turn off... but I've had an intermittent problem with the audio not turning on. I've determined the issue is when I park in full sun at work. Temp usually has to be in the 90s. Until the car interior cools down (usually about 10-15 minutes for full A/C), then stop/start the engine, the radio and sound system (including bluetooth) won't operate. It will turn on for a moment, then snap off before any sound is initiated.
I'm guessing this is some bit of circuitry that defaults off when over a certain temp. Anybody have any thoughts. I could always buy a sunshade, assuming the issue is somewhere in the dash area.
