cdaniel Posted May 16, 2007 Share Posted May 16, 2007 I'm trying to locate instructions on how to update my GPS on my 2004 Highlander. Do I need to go back to the Dealer for this? I have purchased the Update DVD off of Ebay. Quote Link to comment Share on other sites More sharing options...
Leighcm Posted May 16, 2007 Share Posted May 16, 2007 Most likely, you just need to pop out the old disc, and put the new one in. If it doesn't work, turn the car off then back on, and if it still doesn't work, disconnect the battery for 10 minutes or so, then reconnect and turn back on. If the screen ever says anything about "loading" or something similar, just leave it alone until it's done starting up. I'm not positive as to exactly where the Nav disc goes in your car, but check in the back hatch area under the carpet. It's a usually a black box that's about the same general size and shape of a CD changer, and is usually tucked into one side or the other.

MHTHH2006 Posted December 20, 2007 Share Posted December 20, 2007 check out below the driver seat - you may find the drive to insert new CD. Quote Link to comment Share on other sites More sharing options...
