I’ve had my camera hooked up for about three weeks. It will regularly start the 15 second countdown and power off. Sometimes if I unplug it and plug it back in, it will fix. I’ve also started to notice that it only happens mid day, and when it’s sunny. I don’t think it’s ever happened in the morning or at night or when it’s cloudy. It’s hard wired with the Garmin parking cable - fuse tapped to the cigar lighter for the acc and the door locks for constant 12v. The fuses are fine and secure, and the internal fuse on the yellow wire is fine as well. Tried switching memory card and the firmware is up to date. Anyone else have this problem? I’m starting to think something is wrong with the camera..maybe heat issue?
