behind the cupholder in my 2k 180 TT there is a phone jack on the right side of the console, what is that?!?

 

That would be for the factory/aftermarket fone connection?

 

hmmm... I'm curious if I have one...

 

I have one in mine.

 

Its the phone jack for the optional car phone. Those 2 tabs/covers on the right side of the tunnel adjacent to the hand brake would be the mounting point of the phone cradle, and the little rectangular screen looking thing on your instrument cluster would be a mic.

 

Those Germans are so clever!
I swear I learn something new about my car everyday!
