BlueBus: A fully integrated A2DP Bluetooth solution

[killa_e46]

I'll try raising the call volume and report back. All the other hardware in the car has been the same.

Been searching first but no dice. Is anyone running BlueBus with an E46 Professional CD54 (BMW Pn: 65 12 6 924 732) headunit? Was thinking of sourcing one for the better MID but they are pretty rare, especially in the US.

I've thought about swapping to one of those too. Seems like you could do some cool stuff with them

is this compatible with a car with factory nav?

I am. I found mine on UK eBay but the seller wouldn’t ship it to a US address so I had it sent to Baris at carphonics for an amp upgrade + shipping to US. Unfortunately the pixels on my display are spotty and is apparently a common issue on the CD54 with no fix available.

Ted how are the plans for the CarPlay unit coming along? Willing to test it too LOL

I am super interested in the Carplay thing too for my M5. Held off on the other solution for now because I don’t totally like the touch screen — rather control it with the right knob like the Mazda rotary system. Plug and play plus using the commonly available carlinkit adapter is great as well.

Hi, I have a CD54 on the Bluebus, but it doesn't work well. The controls are not stable and you have to press the buttons twice. I haven't gotten the phone right in 2 years. I would not do it. A simple dongle is better on the CD54...

Don't do it -- it's a downgrade. Even though there is more screen real estate, there are no additional """APIs""" for writing to the other portions of the screen. Instead, for consistency, they only allow 11 characters to be written to the screen at a time, just like the CD53.

Have you tried toggling R/T on the steering wheel to see if things improve? I think you'll find that they will.

The BlueBus works well with factory Nav cars

Still in the planning phase!

The plan is to wrap a Raspberry Pi (Probably a compute module Lite) around a bespoke PCB with many of the same components as the BlueBus (for audio and I/O), with the addition of video ICs and a generic input for a backup camera. The CarLinkit dongle will push carplay to the RPi, which will then be output to an HDMI to TTL IC, then an RGB DAC.

The unit will then switch video inputs from the factory Nav to the RPI output whenever you decide to go into CarPlay/Android Auto.

It will also implement the same factory menus and features as the BlueBus.

That's good to know. I'll stick to my CD53 then

That sounds awesome. Excited to hear more about it when you have it more fleshed out.

Besides the screen not being an upgrade, I am curious, what else makes the CD54 a downgrade?

[4getr34]

can you link a DIY on how to install this unit for cars with nav option?

It's less straight forward to use because it adheres more closely to the "R/T" (Radio / Telephone) principle. It makes the UI more difficult to use sometimes.

It's exactly the same as the non-Nav as the pre-wiring is in the same location
