Yes the serial data cable will work to transfer waypoints, routes, tracks to/fro your Garmin 172c. You will not use NMEA-0183, but instead put your Garmin into Garmin or data transfer mode. You will attach the cable to your Garmin's power/data cable. You will be able to use NMEA-0183 mode for real-time plotting with MacENC or GPSNavX.
