Can't comment on the wiring side of things for your 451s, but if you've got it right then you might well have to enable the connection in the software of the Garmin so that you can make the handshake.

As Hightower says it will be configured to talk "Garmin Speak" - in the manual it tells you what to do to make it talk "NMEA speak"
