MULF2 BT Retrofit
I have been planning on doing a BT retrofit and just recently bought a used TCU, BT Antenna, and Mic from a forum member. My car is a 2008 E92 with nav. I went into the trunk tonight to confirm that I had voice wiring already. To my surprise in the trunk I found an MULF2 hi. 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.
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?
