I've had this head unit in my 07 G6 for almost 2 years and last winter would loose power when it got very cold (5F) or so, but would always turn on in demo mode when the car was started, just had to reset everything. This winter it did the same thing but would not come back on until the car was running for about 20 mins no matter how cold it was, and would enter demo mode. BUT here's the weird thing, it never lost power. Now its spring and it sill will not turn on, I got it to turn on one a week ago when I touched the screen, suddenly it popped on. I'm at a loss for what this haunted player is doing.
