I downloaded the AZ topo map by OZ to my Windows 7 computer, ran it and opened Mapsource to installit on my Nuvi 550. Mapsource would not recognize the map. I looked in the Programs file and noticed that for every .img file, there was an .idx file (1 kb) of the same number. Also, the .img files were marked as ".img.idx". Where did I go wrong?!?!
