Bluetooth/Phone

[afnascimento]

Hello,

My 2006 Z4 2.5si comes equipped with the HU on the picture.
Although there is a phone button, it doesn'tn seem to have bluetooth signal or phone menu.
Is this possible?
Is there something missing?

Spotted this on ebay the other day. I know nothing about it but it could be exactly what you need?
