cowansauto Posted November 28, 2023 Report Share Posted November 28, 2023 (edited) Recently purchased a 2018 Journey that has the factory smaller 4.3” touch screen and no back-up camera . We want to install a factory style back up camera to this model. I’ve seen wiring harnesses with a factory camera on them being sold online and was wondering if they would work on a non-factory installed model and be a simple plug and play installation.

John/Horace Posted November 29, 2023 Report Share Posted November 29, 2023 If you search here. You will learn factory unit needs to be activated by either dealer or programs like ALFAOBD. People often just go all aftermarket, dash unit and cam for less hazzle. To not lose current 4.3 built in stuff means aftermarket interface needs to be added at the same time. Door chimes, heater controls etc. Quote Link to comment Share on other sites More sharing options...
cowansauto Posted December 9, 2023 Author Report Share Posted December 9, 2023 So can you simply use that harness that I mentioned above and have it reprogrammed and still use the smaller factory screen set up? Quote Link to comment Share on other sites More sharing options...
