would anybody know if the nav can be added on to an 06 GS from the lexus dealer.

I can't imagine why anyone would want a GPS from Lexus. Spend a couple hundred and get a Garmin and you will be much happier. Buying a GS with the navigation in the vehicle was the worst purchase I ever made.

I wholeheartedly agree. I've cussed the Lexus system ever since I bought the car new. I still can't believe that an inexpensive Garmin will run circles around the Lexus Nav, but it does, hands down. To add insult to injury, when I updated the maps, I lost the 'override' capability and now I despise the system even more. It amazes me that such a fine piece of equipment would use as such a sorry system! I don't know if the next generation nav is any better, but it will play a big part in the next purchase decision.

This is my sixth Toyota/Lexus, all but one were bought new, and this Nav system is enough to make me go to Brand X.

Had my '06 GS430 since new, but new to the forum. Hope to learn new Lexus tricks... :)
