philly777 Posted September 25, 2008 Share Posted September 25, 2008 Hi, Could you please advise how I can upgrade the 2003 GX470 Nav since I can't even locate the DVD for Nav :( Could anyone please post picture for DVD location since I don't have OEM DVD in my vehicle and exact procedure how to upgrade. I believe that the NAV is satelite and I might don't have a DVD ???? It sounds stupid but please advise. Any suggestions where I can the upgrade DVD besides the dealer. Thank you!

Step Hen Posted September 25, 2008 Share Posted September 25, 2008 The navigation drive is located under the front passenger seat. Run the seat all the way forward and then you can get it from the rear seats. I'll pm you some more info. Quote Link to comment Share on other sites More sharing options...
