Picked up a new to me AW '05 4.4i a few weeks back.

The seller told me it had Bluetooth but incan't get my iphone to see a signal to connect to. Went by my local dealer and they said it's not Bluetooth equipped and printed me the option list.

It has option 0640 - Car Telephone Preperation.

If indeed I don't have Bluetooth, is there an easy to understand guide to retrofitting it?

ps. I have the Business CD with Logic 7 Sound System if that helps...
