I only have 2 wires from the radar white & green which I assume is rxd and
gnd.

Rxd is recieve data into the radar. It would be connectered to the Txd
(transmit data) from the GPS.

I have my Furuno GPS connected to my Furuno 1721 radar and my computer and
they both work fine with the 4800, etc. standard settings.

If all else fails, you might want to check if the radar is set to recieve
Furuno CIF format rather than NMEA. In my radar that requires the changing
of a jumper inside on the SPU Board. (this is seldom the problem unless a
previous installation required the CIF change over.)
