I'm aware of the upcoming PDR, however it seems like not many are interested in dash cams? I find the idea of being able to find out what happens around the vehicle when parked entertaining if not reassuring. I'd appreciate if someone with experience can explain how to hard wire a couple of these things to the rear fuse box without tripping anything up. The socket hardwired to need to supply power at all times. Usually the wires run through the headliner but this is a targa top whats the best way to route the wires unobstructed?
