BlueBus: A fully integrated A2DP Bluetooth solution

[jonathanrec]

Hi everyone,
I’m running BlueBus in an E46 330Ci Cabrio (EU car, no factory telephone pre-wire).
I’d like to use the full telephone path (hard MUTE/TEL-ON + Tel Audio ±) in addition to the normal CDC T-harness, so that calls interrupt regardless of the current source—i.e., like the OEM ULF behavior.
Is there a custom plug-and-play adapter loom that:

• plugs into the BlueBus 6-pin telephone header, and
• breaks out the four radio lines to the back of the head unit, plus
• provides two wires for the OEM microphone from the steering-column grille?

Kind regards

I did not buy the adapter, hhmmm might want to message tedbm3 directly.

Thanks man. I've sent an email to [email protected]
I'll report back if I get an answer

Thanks for your help !
I still somehow cannot figure out exactly what I need to order.
Do I simply need a Bluebus and this on top of it :
54-Pin Adapter Quantity ($33)

Correct ?

Thanks again. Florian.

Yes

Yeah I went back to first page and saw someone asked the same question years ago. Haha. Appreciate the response though.

I just installed mine today and it is normal to show CD 7-01 periodically when you push the numbers or change a track?

Yes

As above the CD changer is disconnected and can be removed. There's a 6 pin and a 3 pin connector for. That's for just music playback and control - no phone functionality.

The top module is the ULF or TCU (Bluetooth). You'll need a cable to adapt from that 54 pin connector to the BlueBus.

Thank you for your answer ! I'll wait for more details
When you use the CD changer connector, does a phone call still take priority when listening to the radio ? Is there any drawback ?
I'm kind of sad to loose the CD changer, it's kind of vintage and fun. I like my tape deck behind the nav screen too lol.

Yes I am sure you and I have the exact same optioned car, basically fully loaded. It'll work perfectly fine.

Happy to lose the cd changer lol

Hey everyone !

I'd like to buy a Bluebus adapter for my car with the telephone cable but I am not sure of what phone adapter to buy ?
I looked in the trunk but did not find any connector as described on the bluebus website.
Here are a couple of pictures of the electronics in the trunk.
Is there anyone knowledgeable that could tell me what phone cable adapter I need ?

im sure tedbm3 will chime in but your car is the exact same as mine (euro spec) You plug the Bluebus into the CD changer connectors. You cannot use the CD Changer after that.

Has anyone successfully installed a Bluebus module without having the pre-wiring for a CD changer? I have torn my entire trunk apart and now realizing my Canadian M3 is not pre-wired.

Looks like a ground loop isolator. I use one on my factory AUX connector and bluetooth adapter, as sometimes the stock radio switches from the aux back to radio randomly without it

Thank you! That makes total sense.

[elrichmeister]

Any idea what this aux adapter is plugged into my 6 pin? I just purchased this second-hand and unsure of this extra adapter. Any thoughts?
