Default ---Lost again

OK guys, this is the last try. I need step by step instructions for a Garmin 2010 and an Icom 502 to interface. I have all the instructions, so please dont give a website for instructions. I've have tried both port 2 and three on the Garmin. The problem is with the proper connection at the Icom. The in and out has me confused, along with the two rca jacks(red and whitr). I know for port two to work the violet and gray wire is used. What is the connection at the Icom? Thanks in advance.

this may be what you've already tried. I just had an M502A installed on the new boat but the boat is wrapped up for the winter. The book looks like this... you need to get an RCA jack that will plug into the RED RCA on the ICOM. I don't have the unit here but the pic looks like it is a female red jack, so you need a male (sorry...obvious ). The center lead on your new RCA wires into the positive NMEA (+) output on the Garmin cable. The "shield", or outer sheath on the new RCA is the negative signal output from the Garmin (probably the black wire on most Radio Shack RCA's).

If you get it working seal the heck out of it with rubber tape and/or heat shrink. I'm assuming you will solder the connections, too.

Also, the ICOM doesn't show any indicator on the panel unless you press and hold the DSC/ENT/POS key for a couple of seconds, after which it should display Lat/Lon/Time but until then, you won't know it's getting NMEA signals. Good luck...
