Navigation Updates

[Oily]

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.

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.

I'm reluctant to take a shortcut with a car of this value. I only have 30k miles on it.
