What sorfware to upload topo map to garmin gps?

Question

all king GPS

Answer 1

The standard software for uploading maps to Garmin GPSs is Mapsource which comes with all the maps from Garmin.

You cannot just load any map into a GPS.  You need a map that has been specificaly made to load into the proper brand of GPS.  The place that you get the map from can tell you how to load it.

Since Garmin has made street maps and topo maps for the US and Europe for their GPSs, very few people go through the extreme amount of work to make much for them.
