I have a BlackVue setup front and rear. The rear wiring runs from the camera along the head liner up the A pillar and along the roof line behind the plastic and door seals. I have had 0 issues with any interference. Everything works like its suppose to.
The new iOS 13 Car play Update no longer directly mirrors your phone. You can open what ever app you want on your phone.. text, open maps, etc all while waze is still on the infotainment.
Helps reduce NVH (Noise, Vibration & Harshness) It helps keep vibrations off the glass which reduces wind noise. I'm sure there is more to it but that's the most obvious. Ford does this with the Mustang as well.
Facts it’s a PIA. I still need to hard wire this one. I had the OBD2 port power module for the blackvue but it causes the camera to cut on and off for some reason in the GMC.
Crazy how they come up with these numbers. I have almost a fully optioned 19 Denali almost 69k sticker and I got them to 58K before TTL. My original offer was 56k then they came back at 60K & they finally took 58.
