I used the North America 2010.30 Complete (Canada & Mexico Included) downloading the weird named file from mega upload. I renamed the file to weird.RAR and then extracted the file insede to a folder and renamed it gmasupp.img and put it on my SD card, then i turn my 205w on and it says loading maps, then a green progress bar appears and when it is completed it turns the gps off!!!, Am I doing something wrong? please help!
