my brother just gave me his pristine low mileage (130K) GX470. Had it repainted, and new-trimmed and headlight lens. Looks showroom, inside and out. As no doubt everyone here learned a long time ago, the map system, aside from being a real puzzle, is completely ignored in the owners manual. Apparently there was a training video found on the CD. Anybody know anything about that? What about map updates- is this map system still supported by anyone with US maps? Absent the tutorial CD, any suggestions on how to get started using it?

 

Congratulations on your lucky genetics and having a nice bro! Owner's Manual quest is easy and free:
Go to www.lexus.com and hover over the My Lexus tab. Click on Resources and then My Vehicles Manual
Enter the Model and Year then Submit. The PDF files for the general Owner's Manual are just below.
Scroll down a bit and you will discover the Navigation and Multimedia Manuals. Click on those for what you asked for.

 

The last update for this system was around 2015….its no longer supported….its an old system….

 

Thanks a whole lot! That gets me started quite nicely.
