I am a new user of QGIS, I would like to make a background map with Topolines in gmap or img format.
So I started off with Opendem shape files. I have successfully combined the tiles I want into one shapefile. I would like to use them as a background to view behind an OpenStreetMap map, on a Garmin Etrex 20.
Now I just do not know where to go from here.
Do these files need to be converted into raster files or what would be next?
Can someone point me to a good tutorial?

You should be able to use the "GarminCustomMap" plugin to create the .kmz file, then copy the .kmz file to the /Garmin/CustomMaps folder on your GPS receiver's microSD card. Create the CustomMaps folder if it doesn't yet exist.
