Hello. Just bought my first BMW and after I inserted vin to BMW page I found that, there must be kind on preparation for phone as it says:
S640A CAR TELEFONE PREPARATION - Preparation f tel.installation universal

What does this mean. In the armrest there is gradle for phone but it is empty. No Bluetooth in my car. If I go iDrive to communication, it gives me Belgian tel. number.

Thanks.

And I give link to my car pictures My 525 xd 2007
