mr12volt install - CD changer coding advice
Gentlemen, changing the value of CDMM_CHANGER_3 does not give you CDC, it mearly allows the reading of mp3 files. To obtain CDC you need to tell the CAS, NFRM & CIC to look for the CDC in the first place, hence adding 672 to the VO.
And, as I stated earlier, the fact that there is the multiple CD positions, instead of just one, is the tell-tale. So somewhere you've either got to have done it, or it was already there.

Yep, I should have added that was from you. I was just summarising the thread is all.

You can code the cd changer using bimmercode.
Not sure it's cheapest way but I'm happy.
I bought a fairly (I think) expensive obd adaptor for £85:

I bought the bimmercode app for I think around £35.
To add the changer using bimmercode...
From the 'home' screen of the app:
Headunit -> Expert Mode (toggle) -> 3000 HMI
Find CDMM_CHANGER_3 option and change it to mp3_cdc
CODE -> START CODING

That's interesting. The only coding I did was the bimmercode change and I definitely didn't have multi-cd before.
It it possible that the bimmercode did that VO change as well - behind the scenes?

VO and thr associated CAS etc are one way..and usually the easy way to change major systems..you can often do things at a more individual level to the same effect..fatbaldboy wrote: ↑Tue Dec 12, 2023 4:54 pm That's interesting.

OK, so there is something else here that may be the reason....
With CDMM_CHANGER_3 having a value of "cdc_vorbereitung", this translated into English is "CDC Preaeration", so if you had 694 (CDC Prep) then that would have meant that that value would have been there already. So changing it to mp3 would have told it that there was now a CD Changer. Thus I'll assume you have 694 and there being no need to add 672 to the VO. That then means that no other modules know you have CDC, but that's no problem really as they don't need to
Problem solved

That must be it
This site I mentioned in my first post listed the 'options and s694 was on there under multimedia.
So it came prepped.

I updated my summary on page 2 to hopefully better reflect the facts.

I struggled with mine when I was preparing for the install - from what I can see, the cd changer wasn't even a purchasable option on the 2016 cars.
But it just worked - so problem solved

I think I read somewhere that later cars were technically prep'd but like you say couldn't actually option one. Be interesting what values your vin shows.

The whole Entertainment side of the Z4 is a very complicated pain. So many options and combinations. I've even thought a few times about doing a video on it all but it starts to become troublesome

Your videos are such a brilliant resource. If I was closer I'd have asked you to do my mmi install but as it was you enabled me to do it myself (not that my car is back together yet...)

Glad you like the videos, and I'm glad they've done what they were supposed to do, which is to give owners information on how to fit something. Unlike most YouTube channels mine isn't there to make loads of money, I make a little bit from the Mr12volt affiliate link which is then ploughed back into making more wacky ideas come true!!fatbaldboy wrote: ↑Thu Dec 14, 2023 10:29 pm Your videos are such a brilliant resource.

I have another 7 videos that really should have come out this year, but alas other far more important projects have got in the way. Hopefully in the new year I'll get back to editing the footage I have and get some of these out pretty soon.

Just a learning curve shared. I purchased the latest version with the OEM Mic. I made the mistake of fitting the MIC into the unit Mic input itself instead of the black lead labelled OE Mic. Obvious now but in my hasty approach I plugged it into what appeared the logical. Now my audio to the recipient on calls is crystal
I also updated the unit to the lates firmware and uploaded my own custom splash screen instead of the default Mr12Volt logo. I have included the files needed. Just put it in the root of a freshly formatted USB Fat32 no larger than 32GB and reboot.
