Doing the retrofit in my e92 with voice command and prewired for Bluetooth. No mulf module or tcu in the trunk. do I need both of these to get Bluetooth working? What do each of these modules actually do?
Thanks in advance

Ok partially answered my own question. Found in technics thread that the tcu is also a telematics assist, whatever that means. So I can do it with one module or the other if I just want Bluetooth right?
