Thread: Which to use? Basecamp, Mapsource, Mapinstall, Gmaptool

You may be misunderstanding what BaseCamp can do with images. It can only 'see' *.img files loaded directly onto a Garmin device or on a microSD/SD card inserted in it or one attached directly to your computer, or on a 'virtual SD card' on your computer. You can load so-called 'MapSource' (.gmap folder) files to work with in BaseCamp and send a map img to devices and [micro]SD's using Mapinstall, and that is probably how your Canada Topo was installed [although most Topos are now purchased as downloaded img files or on ready-made microSDs]. Read up on the stuff Caty suggested and if you don't understand something, just have a good play around with the files and program 'hands on' and read BC Help before posting again for specific help.
