Innara Posted July 16, 2010 Share Posted July 16, 2010 Guys I read through a bunch of previous posts however I want to make sure I buy the correct item. I own a 06 RX400h with the DVD nav. I want to upgrade to the latest nav DVD. What specific nav disk version do I need to buy and can you recommend the best place to buy it?

Gryphon Posted July 16, 2010 Share Posted July 16, 2010 You want a Genation 5 version is 9.1. The list price is $199 but you can probably find it cheaper from dealers such as: Park Place Lexus, TX Sewell Lexus. TX Lexus of Shreveport, LA Tom Quote Link to comment Share on other sites More sharing options...
grognon Posted July 17, 2010 Share Posted July 17, 2010 Check it out, but i think that your Lexus needs a Gen 4 nav, not gen 5. Quote Link to comment Share on other sites More sharing options...
andy318 Posted July 19, 2010 Share Posted July 19, 2010 Check it out, but i think that your Lexus needs a Gen 4 nav, not gen 5. Yes, 06 RX400h definitely needs a Gen 4 Nav Quote Link to comment Share on other sites More sharing options...
Gryphon Posted July 19, 2010 Share Posted July 19, 2010 My apology. I misread the table on Lexus.com Tom Quote Link to comment Share on other sites More sharing options...
