new member, good evening

I've had my TT since Sept 1st.
What an awesome car! It just makes you feel so good. I went from expressing an interest in the car to owning one in 10 days.
Needless to say, It was not a factory order but a car that my dealer found within the stock locator system. Although the car has a good spec, (Magma Red extended Leather, Symphony Audio with Bose, Mobile phone prep with multi function steering wheel, Turbine alloys and Silver paint) there are other options I would have ordered. I have now fitted HID conversions for the headlights.
I do have a couple of questions, help please.

Q1. I have the phone pre-installation. The system hooks up via Bluetooth to a Nokia 6300, an old Nokia 6230 and not quite so well with a Nokia E61i. I have bought a cradle for the 6230. My problem is with 'voice recognition'. No matter what I do I cannot get it working. Do I have voice recognition? If I do, does it need to be activated by my dealer?

Q2. Although the audio system can take 6 MP3 CD's, I would like to fit either the Audi USB interface or an after market interface. Is this a simple installation?

thanks in advance
