Antonio,

This photo is indeed that of a very early production ST7000 Autopilot Control Head and support for it ended many years ago. Unfortunately, documentation for this autopilot control head is no longer available. AUX1 an AUX2 ports are likely NMEA 0183 input port and would have been used to support interfacing the autopilot to a NMEA 0183 source of navigational data (in support of Track mode) and/or wind data. The BUS1 and BUS2 ports are likely the control head's SeaTalk communications interfaces. None of these interfaces would support supplying GPS data to a DSC VHF radio. Should you trace any cables which are connect to the autopilot control head's BUS1 and BUS2 ports, you will eventually locate the system's autopilot course computer.
