Question

How can I update my map software for my Garmin GPS system?

Answer 1

If you are talking about the road data, you want City Navigator NT.  There are a couple of options.  You can check with Garmin to see if you are eligible for free map updates at https://my.garmin.com/maps/updates.htm

If you are not, they will point you toward the download, DVD, or SD/microSD card versions of City Navigator NT.  The update costs between $70-100.
