*desertfox615 and kinyo;

Thanks for the tip. I copied the gmapsupp.img file into my device but still can't get a satellite reading. Pls bear w/ me as I ask this: do I also have to copy the mapsource file into my Nuvi? I downloaded and ran it and it's now in the PC. But when I try to access it through All Programs > OSM-PH Garmin maps > a drop down menu of "Uninstall" (with a crossed out icon) and "Website" appears. Is this the end result of the installation?

Btw, kinyo my OS is XP.

Thanks again.
