I bought a 2007 GS450H and the screen says Please contact a Dealer when I press on navigation or any of the buttons on the right side of the screen . The private dealer told me that the only thing it needed was the nav disc. I purchased the disc online and cannot find the location of where it goes. I looked online and cannot seem to find the answer. ??? Any help???

 

On a 2007, believe it's pretty easy based on other posts here (not personal experience).

The navigation ecu is in the glove box. Go to the menu / setting screens on the navgation system and hit eject to confirm there isn't one in there already. The old disc comes out, put in new one, let it load

 

Thank you for the reply. So I am guessing since nothing happens when i hit menu then there must be a issue with the navigation portion .
