I have a gmapsupp.img file and want to add it to mapsource so that I can then install it. But mapsource is not reading it. I guess I have to convert it in some way or other. I looked on the internet and there are a couple of programs but are or too complicated or do not work for me. Do you know how I can convert the .img file to my ppc. I tried adding the file directly to the folder Garmin in Internal Storage of mobile but there was already a file named the same, so i couldn't add it.

Please any ideas...
