Hi, I'm wanting to get a GPS in the not too distant future. I dont want the standard city based navigation maps, i want a GPS that i can load topo maps and the like onto. Anyway, i've pretty much decided on a Garmin unit. Garmin maps are provided in .img format which can be viewed on your PC with their "Mapsource" software. But i want to have a look at some .img maps now to check out the quality of the off road detail. But i cant open the .img files without the mapsource program, which i obviously wouldnt have until i buy a Garmin GPS. So is there any other program around that can view .img files? Cheers. PS, i've done the usual google search and have installed a few programs but none have worked so far.
