jakeg Posted December 15, 2003 Share Posted December 15, 2003 Hi all, i've picked up a '99 GS400 with Nav. i understand that it is a CD based navigation sytem, and i wanted to find out how i update the info on it. i'm sure the '00 version probably had more roads/addresses/POI added to it. Dealer wants $500 for the disc (are you kidding me????) any suggestions as to where i can get a copy of the '00 version? thanks in advance!!

jbarhorst2 Posted December 15, 2003 Share Posted December 15, 2003 I believe in that year it was actually hard drive based. To get the update you have to change out the hard drive. Quote Link to comment Share on other sites More sharing options...

I just purchased a 2000 Lexus GS400, and it is a hard-drive based navigation system - how do update it however?? Quote Link to comment Share on other sites More sharing options...

Be aware that the generation 1 hard drive based systems are only current to July 2004. Quote Link to comment Share on other sites More sharing options...
