I have had Audi UTR front and rear cameras fitted to my S4. The system seems pretty good with clear pictures and the link to the phone straight forward. This is the first tome I have had dash cams so don’t have anything else to compare it too. have two queries? How do you get the parking location to work automatically? It is turned on but doesn’t seem to,automatically record where you have parked. When parked the cameras start working when ever something moves near the car, great to prove dameage in a car park when people just drive off. If the car is parked up for a week or two at an airport won’t this simply flatten the starter battery?
