I was wanting to buy an 02 LS430 with ultra. I like the 2004 features about the navigation. i was wondering if you make the 02 like an 04 navigation with a software upgrade, or do i have to replace the whole navigation unit.

You would have to replace the whole unit.

 

Besides the new blue colored interface and graphical icon buttons on the 04 navigation, what are the new features you really want? Upgrading a 01 or 02 navigation system with the Data 03 ver. 1 will bring you up to the same map database as the 04, but will not provide you the new interface.
