i could use some help here...ive downloaded the file off torent site ibycustopo32.iso how do i change this to a workable file, i really dont want to burn it too cd theres no point its already on my computer and i'm thinking it will take quite a few cd's that i will never use again so whats the point? 7zip gives me the error msg "cannot open file ibycustopo23.iso as a archive can anyone help? i just want to install it into mapsource then transfer some of it over to the gps

im kinda new to the gps thing, my gps 76csx came with mapsource and i was told to download basecamp...to me they both seem to do the same things? what is the difference between the two?

anyone using any of the topo maps from any of the torrent site's ....just curiuos how thats working out

what topo map is the most detailed and up to date for central northern ontario...atving is what i'll be using it for and where can i get it? cheap or free!!! would be the best! gonna put it on a garmin 76csx
