I Installed A Livorsi Speedo For My Back Seat And Want To Wire It Up To My Garmin 2010c Gps, Anyone Know How I Should Do This?

I have the Garmin 3210c and this is how mine worked:

The Garmin 3210 has a 4 National Marine Electronics Association (NMEA) ports. Port 4 ( is reserved for the antenna, port 3 is reserved for the sonar. Port 1 (pin 16/brown data in and pin 17/blue data out). Port 2 (pin 9/violet data in and pin 10/gray data out). You can use either of these ports to go to the input of your speedo. I have smartcraft and it was a blue/white input to the smartcraft system- not sure what wires your speedo has?
