07 X5 center console question

Hi guys,

Newbie here and I have what is probably a really dumb question. I have the aux input in the center console and to the right of it there is another type of jack that sticks out a bit and is not for a usb cable. Anyone know what it is for? I have no idea and a few searches on the site and internet have not revealed an answer. I have the entertainment system so maybe it has something to do with that??

Thanks in advance!!

Are you sure that's not your USB connection? It has a little cover that slides across it.

That's my setup on my 2008 X5 with 6FL option.
