....don't have either, but you said any
help! this link thatCFS insists on calling Vista..
my substitute for real help is: be aware that garmin's usb driver may just be for upload download and not actually a serial
port emulator for nmea
I have a garmin driver, opencpn finds it-it's listed-, but there's no nmea
on it. Try another port, in opencpn's port-choosing dialogue.
Also, confirm with another app that the nmea is
available and thereby confirm an opencpn problem, or not...
"Visual GPS" is my present fave for this.
Vista and Garmin are on my "Do Not Frend" list
