2 - Do I have to create a direct connexion with the GPS?

The GPS can be read through the NMEA output of the instruments or thanks to an independent connexion. The second solution requires an additional COM port but it offers two advantages:

The positions arrive directly and fast in the software as you do not have to go through the NMEA bus. Quite interesting for all transition phases and time calculation (departure).

You can get direct communication between Adrena and your GPS, especially to transfer waypoints or routes.
