STAPE Posted June 11, 2009 Share Posted June 11, 2009 Hello, proud new owner of a 2006 GX470 and new to this forum. I have read a lot of post regarding NAV updates but I am unable to find a clear answer to the following. I currently have the 4.2 version and as part of my deal the dealer is suppling me w/ the 8.1 version. My question is if I do the update will this remove the override feature? Thanks!
