Bluetooth-do I have it or not

[apocalapsi]

Hi i have a late Dec 2004 production X5. I'm not sure if I have a functional bluetooth. I have a telephone icon on my Nav screen and a R/t button on the wheel. I cant use the telephone as all it says is searching . I'm under the impression I have bmw assist and no bluetooth. The module number is 84.11 694738-01. I'm wondering if I replace the module with a newer one will i then be functional? Also would I have to wire in a button in the hand rest where the coin holder is to have a button to pair it or is this not necessary anymore. Any advice would be helpful.
