|I beg to differ. I had an .img file on an SD Card from a Honda GoldWing Garmin GPS. When a made a backup copy to another SD Card the map (.img file) was non-functional. It included an .unl file (unlock) which is basically just a 25 digit code.|
I obtained a hack to unlock the file on the new SD Card to make it useable thereby protecting my original OEM SD card.
Now I am creating custom .img files (maps) and wish to simarly lock them either to a SD Card or downloadable file. I'm looking for non-propriatary software or pssibly a script that will allow me to accomplish the same thing Garmin was able to do.
Thanks for the reply though. Seems this function is not well known as I have not gotten an answer on other forums either.
