Jack,
Make sure your Garmin GPS output is set to NMEA 0183.
In the GPS panel, click "Settings". Set the "Port" drop down menu to "USA19H1d1P1" or "KeySerial". Also set the "Type" to Garmin or Other and the "Rate" to 4800.
If these (or similar) names don't show in the "Port" menu, check your Network System Preferences (under the Apple menu) to ensure that the Keyspan driver is properly installed and configured.
