The GLO-2 requires "bluetooth GNSS". I expected my Garmin Pilot software would 'see' the GLO-2 as another device to be accessed. Instead, it appears that Pilot just sees one system GPS, and Pilot does not know that the GPS in use is actually the GLO-2. But, I am still trying to verify that Pilot, and Google Maps, is actually using the GLO-2 and not the internal GPS. It looks like it is, but I just can't be sure.
