I was installing a satellite radio today and removed the radio, (OEM, non-nav). I noticed there is a two pronged plug at the lower center of the radio rear. Does anyone know what the connector is for? It doesn't show up on the wiring diagram for this radio or the Becker Monaco.

Just curious.

 

there should have been a dummy plug in that connector; i'm not sure what its for, but it doesn't go on the US-spec models. maybe its part of a euro-based radio.

 

Thanks Rob.
