i have a 2006 GS300 basic package with no navigation and rear view camera. There's a guy he offers me the navigation console and the gps sensor ( 2 things saparately) both for roughly about $2g. I research about the installation process and i think i can handle it but not sure if its gonna work. I think it may take some work on the program all the new stuff to recognize each other after installing all of them and i think only the dealer can program it. Does anyone know how this upgrade work?

 

too much of a hassle imo.

 

agreed. get a garmin saves you $1800 bucks
