I guess this is a good thing, but now I am quite confused on how to proceed since all the documentation I read was for the TCU.

Couple questions:

1. This can do BT right?
2. If so, do I till need to install the BT antenna and mic?
3. There were extra uninstalled cables next to the MULF2. Do I need to plug those into something? Do I need to reconfigure the MOST junctions?
4. Why do I have the BT unit but no BT enabled?

Thanks!
1. This can do BT right? - yes
2. If so, do I till need to install the BT antenna and mic? - yes
3. There were extra uninstalled cables next to the MULF2. Do I need to plug those into something? - if it's for the BT antenna, yes.
Do I need to reconfigure the MOST junctions? - usually no.
4. Why do I have the BT unit but no BT enabled? - because BMW decided to leave out 50 bucks worth of hardware when they sold you the car so you can pay a few hundred bucks to get them to do the retrofit.
