I'm thinking of changing the head unit on my Gen III Prius to a Pioneer AVH-4201NEX What I'm wondering is what generates the guidelines that turn with the wheel... is it the camera or the head unit itself? Will I lose that when I change? Thanks!
The lines are generated by the parking assist ECU; on the cars that have them, the camera signal goes to the ECU instead of the headunit, the lines are added, and the combined signal goes to the headunit over a GVIF cable. As long as your new headunit has a GVIF input, it all might still work. -Chap
