I bought a 2019 Nissan Versa SV that had a broken radio at the dealership. The dealership had a 3rd party replace the touch screen radio who used an aftermarket radio. Ever since then the back up camera hasn't worked and the radio says it isn't hooked up. My question is what color wire is the back up camera that goes to the radio? That way I can check to see if in fact that 3rd party (who I have no idea who it is) somehow forgot to hook it up. If it is a simple thing as 1 wire not connected then I can fix that. I would rather do the easy thing than pay for someone else to do it.
