GSJake Posted January 28, 2009 Share Posted January 28, 2009 Hello All, Looking to purchase a 04/05 GS430. Are there any differences between the two model years? I am looking at one with navigation, does this require the $200 DVD to update very year ( I think it will be gen 3) Anything I should look out for? Thanks for your help ahead of time.. -Jake Quote Link to comment Share on other sites More sharing options...
BillyShaft Posted January 28, 2009 Share Posted January 28, 2009 Nav info: 2001-2005 GS430s are all Gen 2/3 Navigation. The 2006 is Gen 4, and 2007-up are Gen 5. You really don't need to update every year. Depending on where you live and how new the area is, you may want to update every 3 or 4 years. If you buy the latest and greatest updates, they generally cost about $250 on discount. If you buy an older version from someone else who updated on craigslist or ebay, you can get it significantly cheaper. Hope that helps, and welcome!
