Garmin MapSource is a commercial application primarily designed to visualize and upload to Garmin mapping GPS receivers the commercial cartography sold by Garmin, and can be used with third-party catrography too.
It also replaces the earlier Garmin DOS application PCX to download, edit, visualize and upload track, route, and waypoint data between PC and GPS receiver, using a Serial or a USB interface.
Free updates of the app are available from the Garmin web-site, but you must have an older version installed for these to work, and the most recent updates do not work well under Wine.

At present the Serial connectivity only works for track, route and waypoint data, but not for maps.

Current Version - 6.16.3
