I'm wanting to add a 2nd backup camera to have one on back of the trailer. Searching hasn't been too successful. Want it to work on the factory nav screen. Anyone else tried this? It's on a 2015 truck.
Should just be as easy as wiring in a double-pole double-throw toggle switch to the reverse camera wiring going into the back of the radio or HMI module...
The problem is that the stupid USCAR/European/Japanese connectors that all of the new trucks use are impossible to get unless you are a supplier and order 10,000 of them at a time.
Its obnoxious as hell for the aftermarket companies who want to make true "plug and play" accessories for these new trucks.
So even if I made a nice little switch setup, it wouldnt be plug and play...you'd still have to cut and splice wires.
