I dropped a 5/16th socket in to the well in the rear driver side getting my bluetooth code. Why was I using a 5/16th on a clearly metric automobile, that's another story...

I came across some connections that I don't know what they are or what they plug in to. Is the first connection for satelite radio? I believe these could mean my X5 is satelite ready. I don't have a DSP radio.



The next connection was on the inside of the area that holds the spare, right by the tail gate toward the right of center.



The rectangle shape looks similiar to the female portion of the OEM Subwoofer.



If so (perhaps wishful thinking) would an OEM Sub be plug and play?
