I just bought a used 2015 limited privately and have been playing with all the shiny new toys. I see the GPS database is out of date by 2 years and that is important in my hometown of Calgary as there are many new areas. I understand that the dealers will update it but can I purchase the map SW myself and get a PC-based mapping program. I have been using Garmin before and they have a map program where you can add waypoints, routes etc then up load to their portable unit. Is there something similar for the built in GPS?
