Yeah, you need to use that original cig lighter adapter. I wired mine up above the map lights.mtietz said:ps: when I use the orignal cig lighter - usb cable it starts just fine when I start the car.
The USB spec requires 4 pins, but mini- (and micro-) USB connectors have 5 pins, where pin #4 is unused. Many dash cam manufacturers have decided that if +5v is available on pin #1 (as normal), then assume the camera is connected to a computer. However, if +5v is instead available on pin 4 (what the cig lighter adapter does), then assume the camera is powered on in the car, and turn the camera on automatically.
