Hi, i have hardwired a nextbase dashcam into my B8. It was quick and easy, the hardest part was finding the right fuse!
You need to piggyback off a switched fuse so that the camera switches on/off with the ignition.
Permenent fuse means the camera continues running and you will have to manually switch it on/off yourself.
Parking mode (which is off by default) works off the built-in battery and records when it detects movement.
All fuses seemed to be Permanent so it was trial and error until I found the right fuse to allow the camera to work with the ignition.
Hope the pic below helps..
