![]() ![]() If the map data is read by 3rd party software, you have no way to secure it. In other words, if you make the GPS units, or the GPS software, you could perhaps integrate a solution that would tie the data to the unit at hand, at the very least make it more difficult to get the data working on another unit. Unless you control the program reading the file, you cannot do anything with the file that would protect it in any way. By its very nature, data on an SD card is meant to be read. ![]() What happens if somebody gets a new GPS unit, are they supposed to buy a new copy of your map? – Apr 9 '15 at 11:12 For non-connected devices (ie, standard GPS receivers) there's nothing you could conceivably do to prevent people sharing some sort of unlock key. The way you protect data (temporarily) is by using a proprietary format, and creating your own programs or hardware to run it (you get better results if you make the hardware). Of some common, open format? Practically impossible.
