    I purchased a etrex 30 and Installed some maps from Topo Canada I had onto a sd card using mapsource. I also downloaded some maps and installed using mapsource. What I didn't realize is that every time I installed a new map, it erases a previous one. How do I go about getting multiple maps installed?
    I read online about renaming the .img file on the sd card in the gmapsupp folder. I can't open the gmapsupp folder. It says it is a "disk image file" and need to download a program to open it?
    Any help is appreciated.

    Thank you
