I too bought a Garmin Glo and a Win 10 tablet. Turns out Win 10 is missing both ends f the process
Open Cpn needs, doesn't have a GPS
sensor nor can it deal with virtual comm
ports. I bought the additional program GPS Complete. You load that prior to loading
Open cpn. Here is the tricky bit. The programs kept trying to use the same com port (3 in my case) so would not
work. I believe what fixed the situation, but I can't be sure, is uninstalling the blue tooth
radio driver then turning on the Glo and it loads it's driver earlier. anyway, the Glo driver seems resident and GPS COMPLETE loads to two com
ports as it should.Opencpn is running fine on my tablet. marc
