2.1.2 Registration
The software may not run with full functionalities and successfully if the map data is not
with legal license.
The license key is calculated based on map code and device ID. If you have not a legal
license of map data, you will be warned by the message "Unregistered map(s) found!"
at the moment you run the software as below. Press OK to check the illegal map data
you use, where a forbidden icon are shown below.
To get a license key, you need to send the Device ID and the map code to the original
distributor to request a legal license key to that map data once you have paid for it.
It would be strongly recommended to register your personal information to the server of
the original distributor once you have the license key in case you need to retrieve the
map data due to the SD card corrupted.
After having the license key for that map region, simply save the *.key file under
\Polnav\Map folder finish the activation process.
