Hi I finished to download the GPS Atlas V70 .exe file and run. When this finish to install create a folder in to my C: unit with the name Bicimapas Inside I have two .img with the name MexicoGPSMAP12_MDR.IMG and MexicoGPSmap12.img and other two file with te extension .mdx and .tdb, and another folder with the name imgs and ther I have 66 .img files. I use gmap tool to export to mapsource like this.

-Open the gmaptool
-Go to options, enable advanced options/select the rout to cgpsmapper.exe
-Go tab files/drag all the .img (this .img is the two for the principal folder and the 66 .img files for the secondary folder)
-Go tab Split/Select the ouput directory files/ Select Compile Preview Map/ Put a name into Mapset name/ Select Mapset FID and put this ones FID 1820 PID 30
-Split All
-And copy the unlock mapset.exe into the output directory (the files gmaptool create)
-Run the .bat file

But when I open the mapsource is nothing there, What I make wrong?? Helpppppp!!!!
