There is this connector in the armrest...what is it for?
 

Is this the bluetooth connector? What is part number and is it good?

Sybian.

Phone cradle.

does that add bluetooth functionality? Part number?

That is the assimilation port that connects you to the hive mind.... resistance is futile
 

I believe that is the cell phone preparation that comes if you get bluetooth. You can order a cellphone holder/charger for your phone (if available) and mount it there.

My salesman said they needed to offer you the ability to hardwire your cellphone to your car instead of bluetooth for legal reasons.

Nothing to do with BT whatsoever. BT module is under front passenger seat.

What is this connection for? I just purchased a very good used 2007 Audi a4 and I'm just wondering what the connection inside the armrest?

I've got the same

See Raistlin's response earlier in the thread then Google search audi mobile phone adapter
