I am having no luck interfacing my old Furuno 1621 radar with my Garmin
GPS45.
I have tried setting the GPS for NMEA/NMEA I/O but cannot get the radar to
display nav data (I have set the Radar menu setting to display data)
I only have 2 wires from the radar white & green which I assume is rxd and
gnd. Cant see anywhere to set baud rate.
BTW - I know the GPS can transmit data as it hooks up fine to my PC.
If anyone has this setup working I'd really appreciate some pointers -
thanks
