alpine_e90m3 wroteJust installed but am getting this screen any recommendations?
Had the same issue on my install this weekend. Did you install the fiber optic loop in the trunk? If you did, you need to remove it and reconnect it to the amplifier. In the US cars we aren’t supposed to stall that loop in the trunk.

Thumbie wroteyeah i coded beforeDid you code the CD player out BEFORE installing?
Thank you for the help!
Had someone on the FB group reach out.
Solution:
Remove the fiber optic loop for the amp and unmute the system😭
I had it right the first time installing however it was just muted

Vostec wroteI get the same green screen or flickering going from reverse to first gear. Only happens first or second time I change from reverse and back. Installed in a e93 335is 6mt without pdc. I’m running the greenyi cam in ahd mode white wire cut. Wired with reverse wire as trigger to a relay to provide power directly from battery like others have. Just curious if you got this figured out and what the resolution was?Have you done the coding before or after connecting the Mr12Volt device?
It's frustrating because there are people out there without this issue. There must be some error during install or a specific setup causing this.
Yes I only have the regular single cd changer below the climate control, nothing in my trunk.
Around two years ago I installed the Mr12Volt device. Afterwards I noticed I had to do some coding in order to make it work.
As I didn't have any experience with coding back then, I met with a local experienced BMW coding guy.
I told him to code the mp3_cdc option and I remember he had trouble connecting to my CIC (because I changed the wiring to the Mr12Volt device during install). But he somehow managed to make it work.
Nowadays I got my own diagnosis laptop with NCS Expert and NCS Dummy.
But with the connection cut to the CIC, I can't look at the coding values. I don't know which cables need to be connected how in order to reach the CIC.
Since I replaced the Mr12Volt device with a new one there is also a new problem now:
Backing up shows a black image without a signal from my GreenYi camera. Returning to D gear, I either get a black screen or a greenish glitching CarPlay image. I have to change the gear to reverse and back to drive an additional time to get the CarPlay image again.
tdott wroteI just updated yesterday to no avail. Still the same awful screechHave you updated the firmware? I haven't had this issue in a long time. I think it only happened once or twice for me, and it's only a loud chirp, not a long continuous sound. Wireless Android Auto so not sure if the phone matters or not.
I also don’t think it has anything to do with the phones that are in use neither. It produces that tinnitus sound through the speakers as soon as I start the car even without a phone or device connected to the mr12volt.
Anyone here with F chassis on NBT and drive mode selection using Mr12volt? I just installed it on my F07 and my driving mode selector up button stopped working. I can go from Comfort to Comfort+ & Eco but UP button to select Sport or Sport+ is not responding.
Hi, looking for help here. I just bought the CIC unit for my F13 prod 2012/07. It has the CIC everything.
I managed to code the car with an cdchanger with esys (ncsexpert for E chassis)
I have installed everything and get into the 12V menu and have sound as etc when connecting with andriod auto.
The issue i can't manage to get my controller to working at all in the 12V but in original menus It works just fine.
Any idea?
Sorry for asking here but 6series forum are dead.
Thanks beforehand.

The CIC unit in the F series cars is different and I know requires different dip switch settings on the p2000 than the E series cars which are the vast majority of the people here.
Remember, the idrive controller knob is ultimately just sending signals on canbus. The p2000 in its current state likely cant understand the signal (because of wrong dip switch settings) or the signal isnt getting there in the first place (because of a loose connection)
drwankel wroteThanks for the input! The thing is that I checked with mr12volt support but they tell me to have all dips off. I also tested to put dip 2 (F06 Cic) but then the unit wasen't detected.MY first thought would be ensuring the dip switches on the p2000 are set correctly, followed by ensuring all connections are tight.

Do you know what dip i should put to on?
I checked for loose connection but as the controller works just fine in original bmw menu i dont think thats it!
If I can't get this figure out soon i hava to send it back.

Anyone here having issues with a new IPhone 17, I have the ProMax but heard all 17’s have a disconnect issue. I can’t stay connected more than 5-10 minutes. The latest IOS update did not help me. I have not downloaded the latest firmware for Mr12V but will this weekend.

I have a new pixel with the same newer version of bluetooth, but don't have an issue with Wireless AA.
Hopefully apple figures it out and issues a software fix. From what I read, it's a software issue and even cars with factory carplay have been having issues.
I have four open tickets with Apple, four friends with Mr12V as well same issue. I also have it on my Cayenne TTS and doesn’t work there either. Wife has the 16PM and it is running IO26 zero issues. It is definitely the N1 Apple chip. They screwed up dropping Broadcom chip. I don’t know if they can fix this with a SW patch. I am going to revert back to a IP16PM soon if this doesn’t get resolved.

I’m having the same issue with the 17 pro running IOS 26.0.1 and CIC mr12volt. Constant disconnects every few minutes on wireless and I have to hold the infotainment knob down to reset in order to reconnect, again only for a few minutes before it disconnects again. Was working perfectly fine on the latest version of android and on an iPhone 13 Pro running iOS 18.
I’ve talked to apple support, who were not useful, and mr12volt support who know of the issue and say they are working on a fix. They told me to use wired in the meantime which I don’t really want to do.
I’m wondering if one of the aftermarket wireless dongles made for OEM wired CarPlay/android auto interfaces that are still working for people using the new 17 pro will work for us too?

I am also having issues with my 17 pro disconnecting from my Airplay attached devices. I I think this is an Apple issue and not a mr12volt. Has anyone tried the 26.1 public beta 2?
Keep in mind that the iphone 17 has an in house designed radio vs the previous qualcomm radio.
Bugs would not at all be surprising as apple lacks the years of experience of qualcomm has in this area.
One of the many reasons I skipped the iphone 17.

vanderv90 wroteI have the same problem here but I just installed mine and was never able to get it to show on cd1 at all were you able to fix yoursHi everyone,
I have a BMW F10 with CIC and have been using a MR12Volt P2000 adapter without issues. Recently, I attempted to update the firmware following the official instructions:
• 16GB SD card formatted to FAT32
• Update file placed in the root of the SD card
• Inserted the card into P2000 and restarted the system
After that, the P2000 stopped working:
• Only the red LED is constantly on (the blue LED sometimes flashes briefly and then goes off).
• The “CD” menu in CIC no longer shows the virtual disks (CD1, CD2, etc.).
• No Bluetooth connection is detected anymore.
I suspect the firmware update failed and bricked the device. I contacted MR12Volt support, but they stopped replying.
Questions:
• Has anyone encountered this issue?
• Is there a recovery firmware or a way to reflash it?
• Can it be reset or revived somehow (via SD or USB)?
Any help, advice, or files would be greatly appreciated!
Thanks in advance!

Is anyones Mr12Volt listed in iOS26 under Setttings>General>Carplay?
I get a list of all cars i've been connected to except the Mr12Volt device for some reason. Because of this, i'm unable to configure the CarPlay widgets.
I'm using a iPhone 14 Pro in a BMW E92 with factory CIC.

Found the solution: You will have to connect the iPhone to the car several times.
Eventually, a device named "CarPlay Device" will appear in the settings list, this is the Mr12Volt interface.
