How did you get the beta mode to access Expert mode in the HU_MGU?

May I know what adaptor do u use? My one is OBDLink MX+ , but I canít get the expert mode on HU MGU HEADUNIT.

You need to email to developer from the app in order to download the beta version and reach the expert mode on Head Unit.

Just coded this into my car, thanks OP

The change in sound quality is stellar, base & the surround sound is astonishingly good in any sound profiles except "Studio" (mainly cuz the profile disables surround sound). I have the HK system so I can't say it'll work on stock or Hi-Fi systems.

Hi,

My car has HK audio. I coded this, noting that the starting value was alev3RAM.

Also, I noticed that, in so doing, this replaced the L7 checkbox and is MUCH BETTER!

I also have the HK audio and not really happy with the sound quality and was thinking of upgrading to Eton.... did you say changing the value to alev4RAM makes the sound better??

And how on earth is this even possible? Is the hardware for HK and B&W the same? (except the speakers ofc) B&W is not even available for 3 series...

I don't think it has anything to do with hardware and everything to do with software.

I have the HiFi 676 in my 330 and this works. I didn't mess with it too much, but to test I cranked the lowest frequency all the way down and my bass went away. So it works...

That is what I meant. For now the HK is the "high end" option and I find it very surprising that BMW decided not to unleash all of the available quality. It is like they've already prepared it for introducing B&W option, by simply reprogramming the head unit (and maybe upgrading the speakers).

rickkap ,

The surround sound is much better with this then the standard HK L7 and even works with SiriusXM. The only down side I noticed so far is that after coding, the equalizer went back to flat so I have to adjust. Even with that, I like it better than L7

I have also just coded this to my existing HK sound system, going from alev3RAM to alev4RAM which as others mention has replaced my Logic 7 tick box with the concert, studio, theatre settings etc.

Sounds good and the graphics look slightly better than before too.

Good find.

I have the Hifi system too but I didnít notice any difference between the various options (studio, concert etc etc). They all sounded the same to me.
When you try and adjust the equalizer, only the two sliders on the ends work. The ones in the middle had no effect when I changed it in my car. The Hifi system has only bass and treble IIRC. I assume the ones in the ends are bass and treble. Thatís why I mentioned in my previous post that it didnít work with the Hifi system.

I can't believe what a difference this has made to the sound quality especially the bass now rocks!!

I did this via e-sys (as i have andriod so no expert mode) so if anyone needs the setting it's:

HU_MGU then
CAFD_3E52 then search for
3002 and you will see
AUDIO-SYSTEM change to
alev4-Ram

Great find... thank you dude

Frequencies are frequencies though, right?

This is just giving more options to adjust?

Well. It gives us more options but changing those frequency sliders don't change the output. Only the ones on the ends does. That's the treble and bass slider I believe. Also, the preset settings don't work in my car.
This is in my car. Not sure how it works for others with the HiFi system.

It works (or more precisely doesnít work) in exactly the same way in my car. I coded it off.
