I also have a 98 GS 400 with navigation and integrated phone. I know what you mean I would also like to get it working. If possible to my nextel. Or even service from anyone. If anyone finds out if it is even possible to get it to work let me know because it would suck just to have it there for nothing. Thanks

I have a 98 gs 400 with the navigation system. All I have seen is updates for 01 and up. To my understanding thats when it upgraded to a dvd navigation.. How about for ours??????? Please let me know what we can do for and update or upgrade.. Thanks
