Fully Integrated Bluetooth Solution

Hey guys!

I'd like to share a project I have been working on for almost a year -- it's a Bluetooth adapter for our cars that integrates as if it were factory equipment, much like the "Intravee". The adapter, known as the BlueBus, also integrates with other vehicles from the E53/E83 era which were equipped with the IBus.

The only thing to note here as that I'm still working on MID integration.

Here's a video explaining the BlueBus: https://www.youtube.com/watch?v=UO9WvRbNzZg

You will also find more information about the project on the website listed below.

Anyways, I'm getting close to having them manufactured, so if there's any interest for it here, I have a "pre-order" form on the project website: https://www.bluebus.dev

I will not be taking money from anyone until I am ready to send off to manufacture, so keep that in mind, please.

Additionally, if you're capable, the project is fully open source, so you can have the boards built and source all of the components yourself, if you wanted .

P.S. The main thread where I have been talking about the development of this module is over on M3F: Interest in a fully integrated A2DP Bluetooth solution? - BMW M3 Forum.com (E30 M3 | E36 M3 | E46 M3 | E92 M3 | F80/X)

Thanks!
-Ted

Intrigued to say the least! Just checked out your other links and I知 definitely keeping an eye on progress - I think a simple way to stream music via bluetooth vs having to plug in my AUX cable and retain standard features would be awesome.

Thanks! It's especially worse now that most phones are dropping the 3.5mm connector :/.

Agreed! You mention installing the additional board in the front headliner area for mic support on the E53, is there more information on the website about that?

I値l dig in some more when I知 home tonight and have something bigger than my phone to browse on. Thanks!

I haven't gotten into specifics about that, but essentially it's a small board that regulates 12v down to 5v and provides it to the mic. Then, it decouples the DC voltage in order to prevent that 5v from hitting the BT device.

You can read more about it here: https://github.com/tedsalmon/BlueBus...r-Installation

I hope they'll be back from manufacturing by then!

That痴 a good read and really, my opinion, a must do item. I think I would much rather maintain the function of the existing mic vs locate and install another mic specifically for the BlueBus. Not to mention I think the factory mic is in a great location already

So to confirm, the to be manufactured BlueBus will come with the correct connections installed and be plug and play in the rear of the car, using the cd changer connections and the module for maintaining the factory mic is also pretty much plug and play simply patching in between the factory homelink and mic via the supplied jumper cables?

I agree, that's why I put fourth the effort to build the adapter board! . I honestly don't recommend an aftermarket mic, but they are absolutely supported and with some work could hijack the OE mic harness to get the signal back to the BlueBus.

The production BlueBus will have all of the OE connectors for the CD Changer harness. I believe you E53 guys have the SES jumper (three pin white connector) in the trunk, so I will be including a wire that will connect directly into the two pin mic input on the BlusBus (it also uses a TE connector, similar to the OE ones).

The front of the car will need the adapter board, which will also include all the OE terminations and will be fully plug and play featuring unique connectors on every end, so you can't mess it up .

Thanks!
-Ted

Great stuff Ted! I follow your thread on M3F and plan on purchasing for my E46 M3 since it's an '02 with Navigation and aux retrofit is not compatible.

Good to hear! Yeah, I surprised when I put my 2002 build BM53 in my 2006 build M3 and AUX went away.
