Peege70

I have a 2000 Ford Excursion. I am installing a AVIC-8000nex. I am looking for some tips on installing this product. I am using a Metra 70-1771 wiring harness to plug into my factory harness. I am not using a backup cam at the moment. I am still trying to decide which camera to use if anybody has any suggestions. I have heard about grounding out the parking brake to get video to work while in motion.
