How do I wire my GPS to multiple devices?
I have a Garmin GPS 12 (handheld) mounted on the instrument panel. I use the
Garmin PC/DC cable to get 12 volt power from my utility lighter, and to
connect to a serial connector.
I have a Furuno 1622 radar with a Furuno NMEA cable, to which I added a
serial cable to connect to the Garmin PC cable. That works great: lat/long,
waypoints, course and speed displayed on the radar.
I'm replacing my VHF radio with one that has DSC and NMEA input. The NMEA
input plug looks like that on a stereo headset cord.
How do I get the GPS wired to that and the radar serial connector?
