momtonikki Posted December 26, 2006 Share Posted December 26, 2006 Hi there, I'm new. I've been trying to figure out how to get an upgrade to my Version 3.1 Navigation System. Do I dare buy one off of Ebay? Will the dealer sell it to me? Any advice for a starting point would be appreciated. My husband has a really cool system in his SC430. Will the upgrade be similar? Thanks in advance. Lisa Quote Link to comment Share on other sites More sharing options...
