Hi Everyone- I’m new to the forum and saw that there was some discussion in this thread about installing a dash cam or radar detector via the passenger side fuse panel. Does anyone have a walkthrough available or is there an online resource that spells it out? I understand the add a circuit premise but having never used one, a recommendation on hardware (I know they sell all-in-one rigs) and the appropriate fuse would be huge. In my Audi’s I’ve always been able to tap right into the positive and negative wires available in the overhead console but not with the 18 Navigator... so much frustration. Any help would be greatly appreciated!
