I believe that plug-in is for an external GPS antenna or external speed/temp sensor. It should be marked with the letters TMP or TMP/SPD (temp / speed).

Thank you sir for the reply. I wonder why this unit would need those devices externally when it already has GPS thus speed and temperature ? Oh well thank you
That is a Nema 0183 connector. Even tho its there I do not think it is usable on that unit.
