upgrade to professional cd

Hi guys, first post here. I just got an e90 and exploring the a bit.
My unit (2009 lci) comes with the business cd. I did not knew any better and I went and bought a professional cd from a 2007 model, thinking that they had Bluetooth streaming. I guess this unit does not.

1) are there any professional cd with Bluetooth?
2) since I bought it does it makes sense to install it? It's an older model so I am not sure if it's got updated during thes. My current unit does play mp3 and the owner of the professional does not know if it does.
3) why there is a button with telephone on my steering wheel? I press it but nothing happens.

Thanks in advance

They put the buttons on the car no matter which options it comes with .
They do make Pro Radio's with usb and bluetooth built in .
But this is only bluetooth phone.
You have to be able to program and maybe add antenna's for bluetooth.
Most pro radios don't come with any options.


If you are interested in better sound quality you will need better speakers
and a amp or amp/processor

Or you might be better off with an aftermarket head unit if you don't want
to add anything else.
