Thanks for jumping in DD.

You will not believe how far you can go by lesson 51.

Garmin GPS's above the basic ones come with a CD containing MapSource, the program you load to the computer.

Garmin Topo Canada is a DVD of Canada Topo Maps which you load to your computer. You then select the ones needed and load them to the GPS.

It is much easier to build and work on a trip file on the computer and then load the the file to the GPS. You can upload additional waypoints, tracks and routes into the GPS at any time.

Note that when you upload maps to the Garmin GPS it will first delete all loaded maps except the factory installed basemap.

Keep the questions coming and we will all learn something from the answers.
