I have a Garmin ETrex Legend that I want to hook up to my new Cobra

supply (if there is such a thing)?
Thanks in advance

Um..if you are talking about using DSC, why would you connect the GPS
to the computer?  It should connect directly to the radio via the NEMA
i/o cable.

Unless I'm missing something.

Which I probably am.

Sorry, I was just saying thats the only cable that came with the Garmin

Ah - thought so.

It's pretty simple. If Garmin didn't give you the NEMA cable to
connect the GPS to the radio, obtain one - the Garmin probably has a
different connector than everybody else uses.

Then it's just a question of following the NEMA color code.

Which is...

YELLOW Wire = NEMA+ Out
BROWN Wire = NEMA- Out

"screen" / Shield = ground/not connected
gray = not connected

Red = +12vdc
Black = -12vdc

White = NEMA + data in (such as FROM another source)
Green = NEMA - data in

Most likely what you will need for the radio is Green and Brown to a
RCA plug or whatever type plug the radio uses.

Check your radio/GPS manuals to be absolutely sure.
