Greg you are the man! Thanks for the response.
For everyone else here is Greg's response. I will wire it up and let you know how I make out.
The AS-SysLink cable is not set up to share the internal GPS from one unit to another, it was only set up for sharing an external GPS. Normally you should use a pair of AS-HHGPS cables but since you have an AS-SysLink cable you can accomplish the same thing. The SysLink cable has three connectors on it, you will need the two male connectors. Be sure to cut them off so that you will have enough wire to make the required splices and to have enough cable to run between the units. Please refer to the attached image which is of the cable connectors (end view) and make the following connections.
Primary Unit Connector (363) To Secondary Unit Connector (595c)
Pin 2 - Bare Drain Wire (NMEA Ground) Connect To Pin 2 Bare Drain Wire (NMEA Ground)
Pin 6 - White Wire(NMEA Output) Connect To Pin 5 - Green Wire (NMEA Input)
Be sure to set the NMEA Output menu in the 363 unit to “On”.
