I also have a 2006 m sport that has the professional head unit with no Bluetooth option, however it does have the phone symbol on the head unit and steering wheel, also there is a wired mic in the roof. I assume that the head unit and steering wheel phone symbols are standard regardless of the units coding to have bluetooth, however does anyone else have the microphone also?
I have a suspicion that a retrofit system was fitted at some point and removed before I bought the car. Also if it was an after market kit how is there anyway I can tell what kit it was so that I can purchase the same system and plug it into my motor.
Thanks in advance sorry if this is a sort of hijack, tried to create my own thread however I could as I'm a stinky noob
