I have a DR650-2CH hard-wired with PMP and didn't have any problems for at least 3 months. Now that the cold weather started here in Vancouver, my DR650 suddenly keeps on restarting. On a 25 minute drive, it will restart itself on average 4-5 times. I keep on hearing Blackvue for your safe driving... Normal recording starting (or something like that). Anybody experienced this? Is it my PMP or my SD card?
