Hi, Steve,
Can I install my genuine .IMG file as an "installed map"?
I think so but i guess this breacks copyrights law. I guess you have a CityNavigator on your streetpilot. If it's on a SD-Card you can take the gmapsupp.img and split it with the gmaptool(needs the free version of cgpsmapper) into a mapset. This can easily be installed in Mapsoure either via Mapsettoolkit or with the from gmaptool created install.bat. The biggest problem should be if you have a 25-sign-installationcode for this map or not. Probably not. There are keygens which can do the job but that breacks copyright law for shure. But may be you have a code. For installing a simple single .img you can follow Valentins instructions. You could do it also with gmaptool (but its a little more tricky, you have to split this single map into a Mapset, sounds crazy but it works.) A quick guide for the installtion with gmaptool you can find on opemmtbmap.org(needs the free version of cgpsmapper): Quickguide for Installtion with gmaptool <http://openmtbmap.org/tutorials/install/gmaptool-install-maps/> Cheers Gert
