navguy Posted August 19, 2010 Posted August 19, 2010 What is best way for me to upgrade software on my Navigation and how can I tell what version I currently have? thx The new DVD updates are coming in October for V10.1. For an 05MY GX470 you will need part number PT219-GEN04-10. Pick it up from your local Lexus dealership for $199. Note - You will have to either eject the old map disc to see the version number (probably V4.1) or check via the touch screen.
