I'm setting up a simple navigation system consisting of my Garmin GPS and an
old laptop running SeaClearII. Presently my GPS is tied into the radio so
that if I have to press the red button the broadcast will include my
position. I'd like to maintain that arrangement.

When I hook into the laptop it will be via a plug-in connection on the GPS
led to the serial port. As a result there will be no exposed data in and
data out wires to lead to the radio. I suspect there's some easy way to
solve this problem, but don't know what it is off the top of my head. How
have others done it?

You will have to make a "Y" connection so that the GPS data out goes
to both the computer serial input and to the radio data input.

There are a couple of wiring diagrams on my GPS/NMEA site listed below
- look on the "Wiring Diagrams" page.
