Does anyone know if this will work? Looks like the prius has the same gen 4 nav as the GS.

A video demonstration of the Navigation Enhancement Kit is provided below. This clip demonstrates the controller addition for the Navigation equipped Prius. It creates an automatic removal of the "I Agree" screen and allows destination inputs for your passenger while the car is in motion. This addition is created without cutting wires.

 

I think I just answered my own question... THis works in the GX so it must work in the GS AND there is a bluetooth add on module... WHOOOOOOOO HOOO!!!! Now all i need is dvd override.

i wonder if they will make one that will let you watch dvd's while driving too. Or maybe this one will let you do it.

 

The nav box is under the seat in the GS? I dont think so. Id make sure this works on the 3GS before buying it. Just my 2cents
