No, the 4 pin connector is at RS-232 levels. It connects to an RS-232 level converter chip. These "UCCM" devices speak SCPI at 57600,8,N,1 I have Lady Heather talking to them (soon to be released, I promise). I have tested it with four different firmware versions (all have some slight differences).
Most of the NMEA data sent from the receiver is proprietary Furuno commands. KO4BB.COM has a manual for the receiver...
Looking at the fifth picture on the ebay link, at the top left corner next to the SMA connector just below R13 is a vertical row of holes. That is the main serial connection and it is at TTL levels.
