Mr12Volt P2000 - Carplay/Android Auto w/M.O.S.T *New Model Update*

Now if I can only remember how to disable the split screen during reverse (I don't have PDC) so would love to get that screen real estate for the camera.

Make sure radar is not selected and click the factory options and I think it's under Decode - set it to 360 degree view and it will be full screen, although it won't show the guide lines

Just chiming back in to confirm the Greenyi 1080P reverse camera does work!

DCT transmission here, did not have to tap into reverse light wire or ground.

Awesome glad to hear. I'm going to install mine later this week for my personal car.

I've had my P2000 unit installed for a few months now. It's perfect for my use case, which is to turn it on when I have to drive more than 5 minutes (only a few times per month). Two problems I've noticed:

• No audio if I start the car in Mr12Volt mode, need to switch to factory radio briefly and then back
• Intermittent half-second power cutout where the screen goes blank and audio stops, it's random as I'm driving down the highway, maybe every 15 minutes

Are these known issues?

I've had the "no audio" issue before on my previous (Black) box, I don't have it on the current one (Grey), is your firmware up to date?...

I've never had either of these issues (11 months with a P2000). The only issues I've had were occasional freezes, but updating my phone's AA software always fixed that

Well, well!!!!!!!! It didn't work!!!
So did the install in the normal way but didn't do any coding beforehand, just the full physical installation. Put the key in, iDrive started up, flicked over to CD and "No Disc" was showing as a single disc only, not multi-disc. So it didn't change anything itself. I even videod that start up.
"OK", I thought "I'll just do the coding the normal way. Connected my ICOM up, laptop on INPA and checked connection and did a fault code check, all normal. Switched over to NCSExpert for coding, Expertenmodus, E89, VIN, CAS..... picked up VIN then failed with a notification of a faulty FA code read!!
Somehow it looks like the new P3000 box has buggered up the VO, so it cant be read, thus you cant code anything on the car.
As I was doing a Cruise Control retrofit at the same time I had to remove all of that as well, reinstall the old stalks and then managed to use Tool32 to reset the steering angle sensor. But I've left all of the Mr12volt installed as its not affecting the iDrive at all. I did check on my phone and could see the Mr12volt box.
I've sent an urgent request for help from Mr12volt, so I'm awaiting a reply.
Fortunately my customer was totally understanding, but I've spent two hours of my Sunday wasting my time and nothing to show for it. Was really hoping to report back some good news.

UPDATE....

I've finally had a response from Mr12volt. They say...
"...Please remove the P3000 unit from the MOST ring before coding"
To which I replied...
" SO is this guaranteed to now show the VO if I do this?..."
And their confirmation...
"Yes, please complete coding before adding the P3000 unit into the MOST ring."

So I've now arranged for my customer to come back to me so I can check this, but unfortunately that won't be until a week on Friday, but I will update this to confirm one way or the other.
TBH, I'm sceptical that the MOST ring connection could knock out the VO for coding, but I could be wrong, we'll see.
As I left the P3000 connected, it wasn't affecting the iDrive in any way, I'll have to take the headunit out, disconnect the MOST and replace it to standard, then unplug the iDrive controller plug and return it to standard also as well as the LVDS cable (I'm taking no chances!). So the car wont see the P3000 at all. Then I'll check with the laptop, if I can access the VO then I'll re-install the cruise I had previously installed and had to uninstall and then complete all of the coding, all at my expense! Moral of the story, just do the coding, it only takes 5 minutes, lesson learned

I have the no audio issue with the older DSP box.

My solution for this has been to not have carplay autostart, and then switch the CIC system to radio before I shut the car off.

Then whenever I start it, I just hit the cd button to go to mr12volt and then start carplay.

This is one of the reasons when adding a backup camera, I'm going the OEM retrofit route, as I dont want that tied to the P2000.

Two things I'm not having luck with:

Can't pick up/end calls with steering wheel control - kind of a bummer because I now have to take my focus off the road/wheel whereas with OEM, I didn't.

Backup view is limited to 2/3 screen, the other 1/3 is still occupied with the PDC overlay (I don't have PDC). Disabled the split screen via OEM settings.

On both of these I asked CS at Mr12v and they said it can't be changed. Maybe I just got a lazy CS rep, anyone else have luck with remedying this?

The camera will pop on and then go back to the factory radio.

It's a little janky because it'll sometimes flash the camera for a moment even if you're not in reverse. Lots of little quirks like that.

You can get full screen by going to the Factory settings and selecting 360 degree view under the Decode Options section.I'm going by memory here so could be wrong on the specifics, but I have it set that way and have full screen for my camera, although guide lines aren't visible in this view (and nor is PDC, which affects me since I have it, but the PDC sound still works at least)

Sorry to repeat, but can anyone advise on how to get the phone button on the steering wheel to work with answering and hanging up calls?

Can't see anything online regarding this. Cheers

I don't think this is currently possible with the P3000. I asked Mr12volt and they don't seem to think others are having this issue but said they don't have a CIC unit to test with. I'd suggest asking them on their site's chat or whatsapp support. I got the same response when I asked about the lack of fullscreen camera and guide lines/pdc visuals at the same time

One nice thing about adding backup cam to the p2000 has been the use of the steering angle sensors to project trajectory lines and it still retains PDC.

The P3000 overlays the trajectory lines, shows and alerts on the PDC, and lowers the volume of any media that is playing. It's strange to have driven the car for 11 years and have all of this in the car.

The P2000 does it better though. With the P2000 you get it the camera in full screen with a PDC overlay. With the P3000 you get a compressed camera image with a separate window for PDC (or you can set it to full screen without guides and PDC visuals).

Speaking to Mr12volt to see how we can bring back this feature.
Keep y'all posted.

I discovered an interesting self inflicted problem today.

For years, I've been having issues where after I take a call, or sometimes when I shift into reverse I would lose audio in carplay.

I had a major clue on a recent occurance, where while I had lost the music audio, voice navigation in waze continued to work. That was extremely odd, and telling.

The important detail here, is I still have the P2000 DSP, and I'm using native idrive for calls and PDC (backup sensors). As such, my phone is paired to both the P2000, and the CIC unit. In addition, my model year is a 2012, so this is a later model e92 and it has OEM bluetooth audio streaming.

What I discovered today is when this phenomenon happens, my phone had actually changed its audio device from carplay to the OEM bluetooth connection for apple music only, even though the P2000 is the active audio device in CIC. Switched it back to carplay and presto! Audio in carplay restored.

This has been plaguing me for years. If I only had my phone paired to the P2000 and not both the P2000 and the CIC unit concurrently this problem would have never happened. Nice to finally have the answer.

This may be the cause of some of my other audio issues as well. I'll need to check. Had no idea you could be running carplay, but the music application can use a different audio device than other apps.

I currently have the P2000,Fitted it the week the new one came out haha but I did get it used for a good price. I've tried their support, may aswell not exist tbh

Did you try doing this in Bimmercode? Not sure if it applies to the p3000 but worth trying at least:

I did this in NCS Expert when I first installed - it just removes the car's voice stuff so that the voice button can operate Siri or Google Assistant without confusing the car's internal system but didn't affect the phone button

Is this all that's needed to get it to work? Because my voice assistant is already disabled, I did it with NCS Expert. Feel like I've missed something else

It worked for me at least. Before I did that, it kept switching out of mr12volt back to CIC.
