I have a 2013 Cayenne GTS without back-up camera and have added GTA Car Kit to my PCM 3.1 for Android Auto interface. It works ok but in the GTS I miss backup camera, and GTA Car Kit has backup camera input. See https://www.gtacarkits.com/product/w...enne-2011-2016

Questions:
1. Do you have a recommendation for a good backup camera to add?
2. It should be easy to get power for the camera for example from the tail lights. Is there wiring from the tail lid to the dash that can be used for the signal?
3. If there is no wire for this already in the car: How do I best run the signal cable to the dash?

TIA,
Ola
