Sorry - a few additional questions on that point.

I'm assuming that means I can convert the img file from post 1 to mapsource and get the elevation data from within mapsource? Or only on the GPS unit if the img is placed directly on the SD card?

If I can use it within mapsource, can I install it with the mapsource version in post 2 already installed and would it show as 2 different maps or would I have to de-install the original mapsource version from post 2 first?
