I don't normally power down the unit before leaving the car (although its probably recommended). Because of that, I'm use to it powering up immediately when the key is turned, or when I plug it in.
I'm such an idiot. On two different occasions now I've powered down and forgotten when I got back in the car. I therefore saw no display come on at key turn or plugging in, and the only response from the hardwire power cord was a blip of yellow when plugged in. No blue display to show its working near the mute button.
Imagine my relief when I realized I had to power it up again.
Anyone else had this happen and had the fear of a dead unit on their hands for a good 5 seconds? Or willing to admit it?!
