If I remember correctly it's looking for the NMEA headers, no APRS headers for GPS data.

The "Serial TNC w/GPS on AUX Port" interface was designed for the KPC-3+ TNC and Paccom PicoPacket TNC's which can send a GPS string down when you send it a Control-E character.  As I recall they send only the captured GPS string, so it starts with "$GP".
