Have you muted the head unit as that then only shows the cd screen.

A very good point indeed, as I've done this on installation before :headbang:Chippie said:fatbaldboy said:switched the CDMM changer to the mp3 value and i can see multiple empty CDs in the head unit (so it worked) but no mr212volt interfaces appears.

fatbaldboy said:So in summary to my original ask:
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

Err that’s what I told you in reply to your original post…. :tumbleweed: :headbang:
Tips for coding with Bimmercode

AnubisZed said: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.
fatbaldboy said: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?

AnubisZed said: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 :rofl:

But it just worked - so problem solved![]()
