Hi all, just wondering what the connectors I have circled below do exactly on the screen? I am attempting to retrofit this into my bog standard spec mini and don't have these connectors. Thanks.
That connector is the Ethernet line that use the audio control panel to communicate to bdc through the air condition panel and IHKA ecu. What audio sys do you have on car now?
I think its for the buttons and vol knob
Ah ok that makes sense. I currently have the base radio, the one with the orange screen. I don't have those lines though but have buttons on the radio itself, guess they're just not used to communicate to anywhere else in the car.That connector is the Ethernet line that use the audio control panel to communicate to bdc through the air condition panel and IHKA ecu.

From basic radio you have to add a lot of wirings and change the head unit. After that you need to code the system. It’s not plug and play!Ah ok that makes sense.

To switch to visual from basic you have to wire:I have the visual basic screen and Headunit to match. Wiring wise it looks like I have most of the cables, maybe not the idrive controller wire but most others. I've been reading into the coding but can't get a 100% answer on what will need coding. I'm willing to give it a go
Check newtis(.info) for wiringsRight so I've got some wiring mods to do. Do you have any diagrams or anything to get me started?
Going to get esys but need to learn what's involved with modifying the FA
Ethernet line is not present with basic radio (check newtis), level oil etc use a different line. Also your HU come from a BMW and not Mini so you have to flash the HU to install the mini SW. for the controller wiring I advise you to solder the cables behind the quadlock (the one big connector) ( pin 4 violet - pin 3 white - pin 1 red/yellow - pin 2 brown/black check newtis for the controller pin order)Just posting thoughts as I go to help anyone looking to do the same in the future. Thoughts may well be wrong of course so please let me know if so.
Looking at the various wiring diagrams it looks like the audio control panel on the screen has to be wired inline with the heater control panel, I'm guessing if I cut the data line to the heater panel and route through the audio control panel then it will work. The idrive controller also needs to be wired in and this looks like a dedicated wire that runs back to one of the K control modules (that I'm yet to work out where it is and how it works).
If I can get the wiring side sorted the next problem is coding, this is something I have played with before with older cars (mainly VAG so using VCDS) but never with ESYS and so in depth so I reckon I'll get stuck there.
It seems like a lot of work to gain a screen but now it's turning into more of a challenge to beat . Sourcing the correct plugs of course is another thing to work out!
I believe my current 4 line orange display radio boost has a microphone and guessing ethernet lines (although can't confirm without looking) because it gathers all the data from the car, oil level etc.
Also got to work out the LED ring wiring, the plug fits but it doesn't light?
Let me check the diagram it says up to 2016 from HU to BDCOk so I need to add the Ethernet line to the quadlock? I've attached a diagram from Newtis which suggests the ethernet lines from the H/U quadlock...I'm guessins these are the ones I dont have.
Ok so I can join the controller wiring inline with the headunit wiring in the back of the quadlock...I guess the data will travel down the same line?
LED ring wise that kind of makes sense... when you say pin 3 and 6 go away... do you mean they swap around or just dont need them? Pin 5 comes from where to pin 1 on the LED ring connector on the screen?
I'm learning....slowly View attachment 69622
This is correctOk perfect. What a project this will be!! So I will need to add the 5 data lines back to the BDC from the H/U?
Controller sounds very easy at least!! The audio control panel sounds ok too, I have ordered the 8 pin plug and will wire this inline with the heater control panel.
Ah I haven't seen the small balck connector on the back of the screen? I will have a look tomorrow and hopefully that'll make sense.
Thank you so much for the help so far, I really appreciate it
You should order a lot of faston (pin) about 30Thats brilliant thank you, how do you connect the new wiring into the BDC? I have ordered an 8 way connector as thats what is on the back of the screen, but perhaps that was the wrong way to do it BMW VW Wiring Cable Plug Terminal Connector 8 Pole 6954526 61136954526 6954522 7625715724060 | eBay
So you have taken a 4 pin from the heater control panel to 4 pins on the audio control panel and then the original 4 pin from the heater control panel then goes into the back of the audio control panel?
I feel like my brain is on fire!
