How is the Navigation map data keep up to date? And does it cost anything for updates?

Most use updated CD/DVD input, and yes, it costs too much.

You're better off with a more user-friendly Garmin 5" unit with lifetime map updates - GPSStore.com

This system is updated over the USB/SD ports but I don't think pricing for map updates has been announced yet.
