    E46 M3 bluetooth module wiring into Business CD Unit

    I purchased this bluetooth module to try and clean up the interior of my car, I've wired the power into pin #9 which is "12v Dir". Currently the module does not seem to power down at all from what I can tell even with the car off, but it works fine. Should the power be wired in the pin #5 which is "12v acc" to make it power up and down with the car? Or should could I run the power to the cigarette lighter as a better option? My worry is that it will kill the battery as is.

    I don't know how deep you are into making this work but I urge you to just get BlueBus. Its incredible, and so seamlessly integrated.

        It's jaw droppingly good. Since you have business CD you're even gonna get a scrolling read out of artist/song stuff on the oem LCD.

        I have a nav equipped car and I'm jealous.

          I'm not OP but, nevertheless, have business CD and am stoked about this

            And you can update the firmware on your Bluebus as time goes by. I just did so with excellent instructions from Ted the developer.

              Ted is great, he's on the forum as well.

              Also, not only are there regular FW updates for BlueBus, but it's also fully open source. Wrote some very quick code to regain memory mirror functionality after I swapped out my stock seats for buckets. Would have been a much more involved project had I not had my BlueBus

                +1 for BlueBus. My car had the factory Bluetooth module and I couldn't figure out how to get it working when I got the car (spent maybe an hour googling and sitting in the car playing with the radio buttons) then caved and bought the BlueBus - took maybe an hour to install and works better than most modern car Bluetooth systems. Also loved being able to retain the factory interior look without needing an aftermarket head unit
