So I just went to the settings menu on Mr12volt (car side) and went down to "more settings on phone". That will pull up a menu on your phone, there's settings for auto connect and stay connected after shut, or something along those lines.

The unwanted connection issue is pretty common. I haven't messed around with that setting yet, but worried it won't auto-connect once I'm back in the car.

For those of you having issues with the phone staying connected after you lock your car is because the car hasn't fully shut down.
The Mr12volt is connected to the power on the car's amp. it takes a certain time for the amp to fully shut down and timeout hence why the Mr12volt is still online.
make sure you lock your car will still stay on standby.

Well, that make sense why Mr12volt still connected.

I'll have a look at that. This issue not really bother me but screen mirroring did. I ask Mr12Volt via WhatsApp but they did not reply.

Anyone know what the new passcode is for Version 3 MMI boxes to get into factory settings is now?

The old code doesn't seem to work..

I have the same issue, screen mirroring doesn't work. (Blue unit). I noticed this after updating to iOS 17.

Help! I installed the mr12volt today in my E61 with CCC. Everything is wired up, but the CD option is greyed out.
The coding is correct.

I had the mr12volt bluetooth adapter from earlier, that was connected where the cd changer was connected. I disconnected the bluetooth adapter and used the bypass loop there, but still nothing..

Anyone?

UPDATE: Found the problem!

When I was moving the new wires between the head unit and the screen, I removed the glovebox for extra room, and what I didnt know was that there was another fiber optic(most) cable just chilling there that I disconnected. So that was the reason why CD was greyed out.

Everything is working now and im super happy with it so far

And also, thank you to everyone that posted and helped in this thread, helped me a lot

Hi guys!
I just found out about the existence of Mr12Volt device two days ago, and I am very interested in purchasing this device.

But I have a question to you guys. Maybe you know something about it.

- I have a 5GT F07 with CIC system. And i have rear entertainment system (two monitors for rear passengers). Because it is old CIC system, there is nothing to do with rear screens except watching DVD discs.
But now i'm curious... maybe with the Mr12Volt unit there is possibilities to run CarPlay or Android Auto on a rear screens, because as i remember there is also possibility to access to CD changer from the rear monitors...

I will be very grateful for your advice

Won’t work - the MMI only hijacks from front/main CIC screen.
What use would you have for CarPlay on the passenger screen though?

[Bashar368]

Can anyone do a quick notes for me and everyone else that’s going to do this upgrade

#1) best place to purchase and which version do we need
#2) which back up camera fits the best and has the highest resolution
#3) i coding necessary

Thank you in advance

2 - GreenYi from Aliexpress

3 - You will need CD Changer to be coded in if you do not have one.

You are right... I just realised how stupid this idea is.
I just don't know what to do with this rear screens. I like the idea to have a screens on a back, but it looks like there is no quality option with CIC for rear screens except DVD discs.
I tried to connect external devices with RCA cable to the back seats, but the quality is terrible. Much much worse than DVD.

[Vlad_Shagov]

Ok, i have another stupid question. The last one, i promise :-)

Is it possible to install the Mr12Volt on the car, but also install the android screen unit, but use it only as a big screen, but stream the CarPlay through the Me12Volt?
Maybe it sound a bit complicated, but as i know this Android screens can be used to show the original CIC system, but with bigger modern screen.

So i mean use Android screen just because it is big and modern, but use it to stream the picture from the CIC, and at the same time CIC will be streaming picture and sound through the Mr12Volt.
So, in another words, Mr12Volt stream the picture to the CIC, and CIC stream the picture to the Android screen.

Anyone found a solution to that horrible high pitch ringing noise when you start up the car?

If the android screen just takes whatever video signal from the CIC it should work. But not sure it's worth it since the oem CIC screen is pretty high quality.

is everyone in agreement that Mr12Volt is the best Carplay option for 2024? Hard to find solid information on these infotainment upgrade options.

[Matt@Evolve]

Hugely happy with it, have a load of customers who are too and it's seeming really reliable day to day too.

On forums it’s the squeaky wheels that are participating. The rest are of us with no glaring issues or problems are quietly enjoying the system and not bothering to chime in. Forum bias makes it look like they’re problematic. I doubt they are. They’re a great update for CIC, I have no clue how they are on CCC.

I believe (and somebody please correct me if I'm wrong) that mr12volt the only one that uses the car's MOST/fiber loop.

I have a car with a Kremersino carplay unit (the later version with the DSP which fixed the lack of bass issues) that uses AUX in, and another car with the mr12volt. To my ears they both sound very similar.

My CIC mr12volt unit recently failed... the right audio channel died, and the USB port died. Went through hours of troubleshooting. It was a model P2000-MD, the one prior to the current model that uses the OEM mic.. was 2 years old so it was out of warranty. Ended up just ordering the new model with the OEM mic support.

That's a bummer. I was hoping it would sound better. The BT audio vs AUX on my kremersino with the bass fix favors the BT for clarity and not sounding as muddle.

If that is the case, my current solution of using BT audio + Kremersino ACP will not be replaced.
