Thanks, GatorJ.
How about the rear sensors?
Is the vehicle and NAV wired for rear sensors?
Mine did not come with them but has NAV.

I'm wondering if it's possible to add sensors to the factory system.

 

i just finished installing my its a peak one that has gps, and ebook.... my nav disc started making like scratching noises so i took it out, id rather be looking at my inst mileage anyways.. has anyone manged to installe sync on no equped vehicles by any chance?

 

In many vehicles, wiring often exists for options that are not installed. Does anyone know if this is the case with FEH/MMH reverse sensors?
What serves as the noise generator for the reverse sensor sounds?
