Phone cradle/bluetooth?

[gramey]

So my 2005 S4 cabriolet has a factory fit attachment on the centre console to the left of the stereo for a phone, my questions are does this mean the car has bluetooth for phone or simply that it's hard wiring for a mobile. The second question is would I be able to get the necessary adaptor to mount my Sony Xperia phone on this bracket or are they obsolete and no longer available?
I don't really want to remove it as I don't want two holes left in the centre console and any second hand consoles I've seen have been in generally poor condition.
Any advice appreciated thanks.

Ok got it, I thought nothing to lose I'll go and try it, sat in my car turned the BT on m phone on and ignition on then turned the radio on and bingo, it found Audi UHV. Once I put the PIN in it flashed up on the screen 'phone' so happy days, just need to find a cradle of some description to hold my phone now!
