How To Update Navigation Maps?

Recommended Posts

Hi y'all, I've been thinking of updating my Navigation maps on my 2004 GX 470 but all I read on the forums were DVD update discs. My 2004 only comes with a CD changer and a rear DVD player on both the front seat's headrest. Here's my dumb question....how can I update my Navi maps when the updates comes only on DVD format?

You have a nav system that has the DVD in it I think it is in the rear.

Try this http://lexus.sewellparts.com/accessories-catalog/Service/GX470-2004/4444.html

Make sure it is the right one and also look at the instructions that will show you everything you need. Also I think if you mention you are a member they will give you a discount on your order.

The navigation DVD player is under the front passenger seat. Pop the cover off and press the eject button, you can get the DVD out and replace with an updated one ($199 from dealer).

Hi all, can someone tell me if there's any of this version that comes pre-loaded with Nigerian map. I have a GX470 (2007 model) and I will like to have my local maps on it. Any solution for my case? Thanking you all ahead...

I just received an email from Lexus today about Nav upgrades. You can purchase the latest update from Lexus for the 5th gen GX470 for $99.00 thru the end of the year.

Picked up my new nav dvd today. No more agree button. I get a warning not to watch the screen while driving and then it goes to the map screen.

I see this is an older thread I guess I’m bringing back from the dead. I am a longtime owner of my 2003 GX470, and I JUST NOW found out I can update my navigation. Got under the front passenger seat, popped my DVD out & attached is my disc. My question is, what is the newest navigation disc I can put in my 2003 GX470 that will still be compatible and run smoothly? Are the most up to date versions of the nav discs too advanced for my system? Any input will be helpful before throwing out over $100 or more for something I can’t use.

The final update for the gen 2/3 nav system like you have was in 2013 - the part numbers, which I think are for either west or east of the Mississippi are:

West Dealers:  PT219-GN23W-13

East Dealers:  PT219-GN23E-13
