Chris,

You're talking about the DB25 connector, right? That's known as X18500 on the E39 not sure about the E53. In any case, the BlueBus will not incorporate that 54 pin connector because it's NLA the pin outs vary wildly between different TCU types, and would add unnecessary bulk to the board. Instead, users will be given an 8 pin male connector along with instructions on de-pinning the 54 pin connector and inserting those into the provided connector. You only need to de-pin 6 wires from that 54 pin connector.

On to the DB25 connector: It has all the right signals for the TCU, so I don't see a problem selling a compatible male to BlueBus connector, since that is a bog-standard connector still used to this day.

Code updates already happen via USB connector :). I've got some support for code updates via a phone app, but I'm not sure I'll go down that road as it's not as reliable as I would like.

Thanks!

Hi Ted!

Yes, I'm referring to the DB25 connector that the older E chassis cars used before Bluetooth and the 54 pin connector became standard. BMW used to sell an adapter but it's long gone NLA. Sounds great on the adapter!

Sounds like an awesome unit, thanks so much for supporting the older cars, they truly are what BMW should be in terms of driving dynamics.

Chris,

Excellent! You're welcome! I'm an E46 M3 owner, which is why I started this project. I also think that this era of BMW is the only relevant era anymore.

For those wanting to make their own DB25 to 54 pin connector (since it's NLA), you can assemble it with these parts:

Some standard 2.54mm male to female pin headers should do well to be used in the 54 pin socket.


Thanks!

Hey guys!

Just FYI, Ryan @ E39Source reviewed this product:

Nice Dude!

I'm sure owners with stock audio system will be happy!

So did I understand correctly that this will be available next month?

Yes sir, Jan 2020

Shit, I can keep my DSP and factory MID and now get phone calls over my stereo and Bluetooth my music? Yes please!!!

Hey guys -- Yes, these will come in from manufacture next month and begin shipping, though it's likely going to take me a couple of weeks to make it through all units as each one must be tested and programmed.

Yep! Glad you're as excited as I am :)

Thanks!

I've been trying to keep these "out of mind" until they are available.
