The better Garmin camera is in front, 66w, and it’s tethered through the Garmin app to the rear dash cam mini, I have their parking mode cable in both cameras. The front grabs the constant hot and ignition hot to the right of the gas pedal ( there is a thread on it) and I converted the rear 12v plug to constant hot, and ran a wire down the drivers side trim to the rear camera for ignition hot. I also posted the. Thread where I fished the mini usb plug through the back door panel. That sucked, it looks like it paid off. I was reading the police report last night and the Kia driver was cited for going to fast for the conditions.
