Pied1946 Posted March 8, 2014 Share Posted March 8, 2014 GS3504: Look in your owners manual, it's a user friendly upgrade. Just follow the instructions step by step that come with the new disk. ONLY buy it from Lexus though. Not EBay! My '06 GS430 hadn't been updated since factory shipped and the cost is over $100, but there has been quite a few road additions and changes since then, so I took the plunge and it only takes a few minutes. If there hasn't been a ton of changes in your driving area, I'd say leave it for a few years, but if you regularly travel to new areas of the country I'd go for it!

1990LS400 Posted March 9, 2014 Share Posted March 9, 2014 Navigation updates for the 2010 GS350 are on USB flash memory and are applied by a Lexus dealer. It is not like the older DVD based Lexus navigation systems which could be easily updated by the vehicle owner. Quote Link to comment Share on other sites More sharing options...
