I have my GPS interfaced with a Furuno and the "lollipop" is a valuable
feature. Obviously the first step it to connect the NEMA Out wires from
your GPS/Laptop. I have a switch on mine so I can choose between the output
of the GPS or the output of the Laptop. Sometimes I use the GPS without the
laptop on the bridge and other times I use the laptop to drive the
autopilot and feed the input of the radar. The next thing it to find out
what baud rate the radar will accept. You will probably have to go into the
setup menus of both units and enable the output and set the baud rate on
the GPS and Laptop. You also may have to enable a NEMA import in your radar.
I know this sounds like a lot of stuff by you only have to do it once.
