Just had the NAV in my '99 updated to the Sept 2003 version. Nice. Changes are subtle but nice - new (smaller) font size and very bright screen, with a white background. More POI's (1 million in new update). Real nice. I'll be testing out in newer communities built around here to see if this update is as promised by Lexus. BTW, I paid $260 installed. Part was $230 and labor was $30. Real cheap considering another dealership quoted $400 for the same.
