Mr 12 Volt MMI MOST box, glitch problem solved !

[inkey$]

Ah, okay. Makes sense. I installed an MMI in my 2016 Mini Clubman but thats an F car and iDrive4. £200 delivered and easy/glitch free.

Definitely sounds like a faulty box, personally I'd recommend insisting that it is replaced.

As for updates,

Firmware (MCU) update - This is performed via the on-board microSD card slot, full access to the box is required. The last Firmware update was October 2022.
Software update - This is performed via USB connection, a lot easier to perform as you don't need to get to the box. I've been informed that this is only really required if there is a problem with the software, ie; compatibility issues.

Did they suggest a software (USB) update?

No they didn’t…I didn’t see any references to s/w updates via USB?

Just firmware updates via microSD card..which I did to the latest version..


They’ve gone strangely quiet now ref box and warranty..fortunately I bought it May 2022 so it’s still under warranty..

It’s very irritating as it impinges on my other upgrade plans as now with all the centre console out and other disconnects I can’t move the roof to get access to the boot etc…

That’s strange my software is showing 20221019B
When yours is latest one with “A”?

Software update video released a few days ago....

And I have neither A or B

[B21]

Weird…I downloaded it and burn it two days ago…

I see my s/w and Bluetooth versions are older but the h/w revision is the same?

Date of system shows shows August 2021 when I bought the box in May 2022..

Where do you get the download from ?

Ignore that you have to email them to get it..

Hopefully less buggy..

The Chinese after 5 days of intense and at times banal discussions and with an overwhelming weight of evidence have thrown in the towel and will replace the unit.

I doubted they would plus I’m under time pressure so I ordered a parallel unit….

So one way or another I should bottom this out plus then I can sell a brand new unit as tested and proved

[B21]

In the meantime..doubtful of getting a resolution I bought a second Mr 12 Volt box to sort things out one way or another…

So box arrived today and plugged it in…

No video glitches ..some strange failures on audio handover when flipping between native Bluetooth media streaming and onboard CD and CarPlay…but I’ll sort that out..

Software has been updated and in the process there is now no opportunity to remove the Mr12 Volt boot logo and replace it with a BMW logo….heh ho..

Looks like I’ll have a brand new MMI box to sell if anyone’s interested ?

[AnubisZed]

Glad you've got it sorted

[B21]

Glad you've got it sorted

Yes getting the wiring sorted now and using your install location

I had a MMI box fitted a while back that had similar issues, removed it, replugged it, software updated it over and over again but a the end of the day its a box of chinky tricks and mine went in the bin. Mine was not from Mr 12 volt but i would put money on it being identical inside.
If I was going down this route again I would be swapping out the old 1980 style screen for the upgraded android versions

Most these things coming from China are made in just a handful of factories if that but have multiple sellers on Aliexpress / Alibaba, some claim to be factories but are not. Those android boxes are not without their problems either.

Yes I know I own a dropshipping store.
The android screens have a lot better reliability than the MMI boxes, not aware of an android 'box' though, do you know of one?

The boxes are not identical for several different reasons..

Incremental hardware iteration for one..subsequent models use later, with experience, better specified components and revised chipsets

Mr 12 Volt uses the MOST bus which is unique amongst all the other MMI boxes in using optical digital audio connections.

Buying through a UK represented company in the case of Mr 12 Volt does give you rights, albeit maybe slowly actioned.

In my case I got a new unit FOC in the end.

The screen in fact was first used in 2009 so it’s not a 1980 design.

I looked at the android screens but if I had a choice I’d still go with idrive.
