vickisj Posted December 15, 2008 Share Posted December 15, 2008 I was wondering if there was an update to the 2004 Navigation system installed in my 2004 GX 470 and if so how do I update it? Particularly search features for businesses would be nice. Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted December 15, 2008 Share Posted December 15, 2008 Sewell Lexus might be a good place to start. I found this web page from them on the 2007 Gen 4 update but its marked "discontinued" - maybe there is a later one: http://www.sewellpartsonline.com/parts_det...90137&all=Y I've bought quite a bit of stuff from Sewell -- good service. The current discount code from the ClubLexus form is “CL911M” although I've generally been given a discount without using a code. You might want to give them a call to make sure you get the correct update version: 888-909-6633 Don't know if an update would help you locate businesses -- the databases in navigation systems from car manufacturers are often behind the ones in portable navs like the ones from Garmin. EDIT!: I see on the Sewell website that your 04 GX has Nav generation 2/3 instead of the version 4 in the 04 LX -- Sorry! Quote Link to comment Share on other sites More sharing options...

OLDSCHOLEVO Posted December 15, 2008 Share Posted December 15, 2008 you can get a 8.1 update from any Lexus dealer for $265.00 plus tax. Quote Link to comment Share on other sites More sharing options...
