[ntp:questions] Problem troubleshooting gps/pps on freebsd 8.1

I want to configure a server that uses a garmin gps with pps to
discipline the clock. I've basically used this as a guide:
The gps is connected to the serial port and the pps signal to dcd. I
run ntpd 4.2.6p2 and freebsd 8.1.
I can simply not get the nmea reference clock to work and I don't know
how to troubleshoot it.
This server will not have access to the internet when I get everything
to work but for testing it will sync to the internet servers but never
to the gps.
[root@ ~]# ntpq -p
remote refid st t when poll reach delay
GPS_NMEA(0) .GPS. 0 l - 16 0 0.000
Running ntpd -d I see this so I guess ntpd sees the gps:
nmea: gpsread 70 $GPRMC,033730,A,5926.7899,N,01758.1371,E,
nmea: gpsread 66 $GPGGA,033730,5926.7899,N,01758.1371,E,
Any ideas where I should start?
