I am looking for a (preferably free) replacement for Garmin n-route. I have Satellite internet so need to be careful of download size because of bandwidth limitations. How large (mb) is your program? I have the United States in OSM routable tiles already in img format for mapsource. Could I copy them and somhow convert them to your program? Or do I need all new map files. Also, is it possible (for a price) to get all the maps For the US, or US and Canada on a CD for your program so I don’t have to download them? I did not see a list of compatible GPS Devices, and would like to know if my Garmin 76CS will work with your program. Thank your for your help.
