Good info, I have been looking for information on this topic. I knew there was a reason I joined this group.

You probably need to hook up all 3 wires: DME, power, i-bus.



Yeah. The whole ZCP panel confuses me. It has almost all the circuitry of the right side of the multifunction panel, yet only acts as a momentary switch. It uses no power or i-bus and I have tested that the only thing it does is connect 2 wires when the track button is pushed. Sad.

Since all 4 wires to the multifunction are being used, BMW could not add track mode to the wheel without changing the connector, the slip ring, etc. Still, they should have been able to add it to the dash, the column, or somewhere else.

Next tell me you're in the DC area and willing to do installs

Where would the best place be to buy the MFL panel? Can't find the part on Tisher.

*edit* looks like this is it.

By bluetooth activation, do you mean the talking man button on the steering wheel that activates voice commands? You think connecting a momentary button to the wires in the arm rest console will activate voice control? The OEM steering wheel talking man button has different responses depending on how long it is held down (i.e. a short press vs a long press). Would this still behave correctly?

Post pics, that would be great. I am not clear what the LCM module has to do with this retrofit...

No, I'm referring to the console button on ULF systems, this is an 18-pin connector. I'm not 100% how this would behave with TCU-specific systems but would assume it should be fine since the steering wheel buttons are non-specific.

It was my understanding that the BMW ULF pairing button that is typically mounted in the center arm rest console is no longer available and that a momentary interrupt switch can be used instead. What I don't understand is that the similar talking man button on the steering wheel is interpreted as two different iBus commands depending on whether it is a short press (interpreted as redial) or a long press (interpreted as activate voice control). I was wondering whether a momentary interrupt switch installed in the center console armrest (just like the ULF pairing button) would work like the talking man steering wheel button for TCU systems. Seems to me that the talking man button on the steering wheel has to be more than a simple momentary interrupt button and has to send specific iBus commands when pressed.

The button is only a momentary switch with backlight - no specific device signature is present.

Default Cazz, can you confirm retrofit parts/numbers in doc?

Looks like I'll soon be the owner of a 2006 ZCP, flying out and driving home 1100 miles, so I'd like to do this for the drive home.
I went to the dealer asking about the retrofit part numbers in the PDF, but there's not much description. It appears from cost and weights shown that:
65 71 0 021 159 is the kit one needs for a ZCP, but they don't list the parts you get. This p/n weighs about .2 lb per local dealer. No way to know if it is the upper cover with buttons plus the harness, but hopefully so.
Likewise,
65 71 0 026 223 I'm guessing is the whole steering wheel based on the $500 + price, but again no parts listed. Forget the weight but think it was 2 lbs.

Maybe you ordered the top cover/buttons only and made your wires? but the link isn't current. Even so, can you provide that part number and approximate cost? I'll look it up on realoem I guess, but I'm willing to buy the kit in these remote/short timeframe circumstances if I can verify that's what I need. I can do the M-mode button relocation after I get home. The point here, question I'm trying to clarify is these parts listed in the PDF appear to be that you need one or the other, not both, correct?

Thanks for any answers.
