I tried that and it does not work. I am in the process of downloading the Mega file. Do I follow the same procedure when putting it on the SD card ? I bought a 2 GB card today, it should be big enough for the file. Do I create a Garmin file on the formatted card? Do I change the name of the file to gmapsupp.img ? I want to do this right, my knowledge of GPS systems and computers is limited so I need all the help I can get.
