So many times I've said I can't use a GPS that is disabled when needed. There's no reason why my passenger can't navigate while driving. I saw the aftermarket harness, but can't spend $175 on it. So this thread was exactly what I needed. I installed the Navi safety override switch, and since I was in there I also installed the rearview monitor switch.
The wife wouldn't let me put the switch in the dash fascia, so I put them both on the passenger side where she can hit the switch and tap up a new destination.
Found my super black 2013 Leaf.
