hi, my is300 didnt come with navigation, so i bought just the oem navigation screen on ebay. I was told the the 2003 and up is300 come prewired for navigation. So when i went to took the middle tray out and ready to install the navigation screen i didnt see any wire or couldnt find them. does anyone know where the wire for the screen are located. or does some one know where i could buy them. thanks

 

You just bought the display unit itself? You might still need the main brain.

 

yeah i just bought the display itselft. You mean the navigation cpu. but i hear that the is300 comes already prewired?

 

Here's the brain you might need. Try to buy it cheaper elsewhere.
