I was on the Interstate today, and my RX-65 just went blank. The screen "disappeared." I actually had the cigarette lighter plug plugged in, and the light was green on it. Hitting the button on the left, which I believe is the power (CORRECT?), did nothing. I unplugged it and plugged it back in (Edit-->) and it started up as usual. Strange.
Had I had the thing hardwired as it usually is, I would have plugged in my Stalker ATR Ka gun which was in the passenger seat in order to get an alert.
