Would anyone be kind enough to post MD5 sum of the unlocked .img file? I am not sure if I could join the parts and unrar correctly, and then unlocked it. The final image turns out to be of size 688832512 md5sum 84a267b88e51a8f29b7b3e2aff643fa6, is this ok? Somehow my nuvi 1100 doesn't recognize it (copied the file as gmapsupp.img in Maps folder of SD card).
