allancg1 Posted March 29, 2009 Share Posted March 29, 2009 I have a 2005 RX330 with the Gen 4 Nav system, I assume. I want to update to the 8.1 that came out this past fall. How do you install the new DVD with the updates for steets, POI's, etc.? Quote Link to comment Share on other sites More sharing options...
