Oily Posted February 2, 2008 Share Posted February 2, 2008 I am looking at updating my 2003 LS 430 navigation. I live in Calgary, Alberta Canada and our city has grown so fast most of the new communities are not digitized in the old version 2002. Does anyone know of an inexpensive way in which to upgrade the nav system? Thanks in advance. Oily Quote Link to comment Share on other sites More sharing options...
amf1932 Posted February 3, 2008 Share Posted February 3, 2008 The only way you can update your nav with the most current information is to buy the 7.1 nav disc from Lexus. I don't suggest buying a bootleg disc that are sold on some of the auction websites.....they could possibly screw up your system. Quote Link to comment Share on other sites More sharing options...

Thanks Alan I'm reluctant to take a shortcut with a car of this value. I only have 30k miles on it. Quote Link to comment Share on other sites More sharing options...
