I'm trying to do this retrofit. I'm using the cable from One-Stop-Electronics. NCS Expert version is 4.0.1. Daten files version is 2.51.2. Everything is installed under Windows XP Pro 32.

The new BMW Professional radio arrived with USB and BT enabled. The internal menu reports manufacturing date of 01/2014. When I connected it to the car, both USB and BT worked right away, but the gong was overly loud (due to the radio being set up for "stereo" sound system) and the voice command language was German. I.e. a typical situation with many posters here.

Doing SG_RESET on the radio made both USB and BT to disappear (again, expected behavior). However the gong was still loud, meaning that the radio refused to switch to HiFi mode. Adding any codes to VO and doing SG_CODIEREN or SG_RESET on anything did not bring neither USB not BT back. The gong was still loud.

Changing the production date from #0910 to #0311 and SG_RESET on the 2URAD did bring USB back. So, now I have working USB, but the music doesn't sound right since apparently the equalizer is still set up for "stereo". And the gong is still loud. And there's no BT or Voice Command functionality. I did everything I could find in the forums, but I can't seem to progress any further.

This is my current VO

Code:
E90_#0311&LCSW%0A76$1CA$249$255$2S2$2VB$403$459$465$481$497$4AB$4NE$520$521
$522$524$534$544$563$570$5DS$645$663$676$693$697$6FL$6NN$704$760$823$840$845
$850$853$876$8S4$8TL$8TN$925$992*PM53-B080-EMOA-OSPS
As you can see, it has $6FL, $6NN and $663. I wonder if these's some simple mistake in my VO set.

I can successfully read the 'FSW_PSW.TRC' from 2URAD. It shows a lot of entries with 'hifi' in them like

Code:
...
AUDIOSYSTEM
	hifi
AUDIO_SYSTEM
	pl2_hifi
AUDIO_SYSTEM_RAD1
	pl2_hifi
AUDIO_SYSTEM_RAD12
	pl2_hifi
AUDIO_SYSTEM_RAD22
	hifi
VOLUME_ADJ_1
	e90_hifi
FILTER_FZG_BLOCK_1
	e90_hifi
OUTPUT_GAIN_SYSTEM
	e90_hifi
SOUNDAUSSTATTUNG
	hifi
DEF_GONG_VOLUME
	e90_hifi
OUTPUT_GAIN_FRONTLEFT
	e87_hifi
OUTPUT_GAIN_FRONTRIGHT
	e87_hifi
OUTPUT_GAIN_REARLEFT
	e87_hifi
OUTPUT_GAIN_REARRIGHT
	e87_hifi
VOLUME_TABLE
	e90_hifi
...
and so on. These are just some examples, originally scattered across the file. There is a huge number of entries with 'hifi', so I won't post them all here.

However, a search for 'stereo' produces a small number of results, all of which are here

Code:
OUTPUT_GAIN_SUBWOOFERL
	e87_stereo
OUTPUT_GAIN_SUBWOOFERR
	e87_stereo
VOL_TEL_MAX
	stereo_mulf_e87
AUDIO-STANDARD
	stereo
There's also a number of "suspicious" entries like the following

Code:
AUDIO_SYSTEM_TOPAMP
	not_active
TOP_HIFI
	nicht_aktiv
EQUALIZER
	nicht_aktiv
(On the second thought, there's nothing suspicious about them: my system is not "top hifi".)

The internal menu in the radio still reports "Sound system: stereo" in the "Audio" sub-section.

Trying to do SG_CODIEREN on the 2URAD results in an error (same error many posters here already reported, see the attached picture). I'd appreciate any suggestions on what to try next.

Hi.

Im a newbie here and have just bought a BMW 120i (2012) and have a few questions that maybe someone can advise on. I have been through a few of the posts on this and other forums and i am a little confused.

I have bought, but yet to pick up and E82. When i viewed it, it turned out there was no bluetooth phone and also there was only an aux jack socket behind the hand brake and this meant i could not plug in my ipod and control from the radio. But after reading I am thinking i can change the radio from a business to a professional radio/cd.

So my questions are :

Exactly what model number do i need that had all of the above?
What is the model number of the microphone that i need, which i think would be located in the steering wheel?
Would the USB for the ipod be located next to the jack point with another facia or in the glove compartment? Can I have model numbers for each?
If I decided to add a separate DAB module at a later date, are there enough inputs?
I keep reading about having to 're-code' it. Would i have to? Can I do it myself, or where do i take it?
Is there anything else i would need to purchase?


I basically want to be able to answer the phone and use the phone book using the current steering wheel controls and also be able to select different playlists etc, without sticking on other switches to the dashboard etc. I am looking on ebay and there are different models etc and i am simply trying to quote and see what i need to spend. Maybe i could sell my old radio on ebay to get some of my money back!

So many questions i know, but i thought i would write this, as this is more specific to my model and have also been racking my brain!!

thanks so much in advance for everyones else.
Please be gentle with me!

BMW E87 (Europe) Built-in Bluetooth Professional Radio/CD

Hi Joe, Thank you for your sharing and information. I have the player which is attached. I would like to replace this with my basic bmw business player. As far as I understand the new one which I got has bluetooth. Do you confirm this? Would you please indicate the needed cables and spare parts in order to retrofit?

In addition is there an extra bluetooth anten? I think it is needed. Please advise.

Furthermore I live in Istanbul, Does coding differ from the your format? Could you please advise about coding and if possible its shortcuts?

I am BMW addict

Batuguler,

The parts you need depending on your model are here:

Keep in mind that if you dont have a e93 or e88 the mic reference is different!
Because convertibles have the mic at the steering wheel column but others have it at the roof lights module!

For e93/e88:
61138377072 x1 -> 3 pins Connector
61130005197 x4 -> Female Pin
61138384550 x1 -> 12 pins Female Connector
61138387206 x1 -> Connector housing
61316950266 x1 -> Steering wheel column cover
84316977740 x1 -> mic
61119129360 x1 -> Coaxial fakra wire for USB
84109237653 x1 -> USB/Aux Socket

Other e9x and e8x:
61138377072 x1 -> 3 pins Connector
61130005197 x4 -> Female Pin
61138384550 x1 -> 12 pins Female Connector
61138387206 x1 -> Connector housing
84316938762 x1 -> mic
84106936148 x1 -> Mic housing
61119129360 x1 -> Coaxial fakra wire for USB
84109237653 x1 -> USB/Aux Socket
I have just recently fitted this from the Basic Business head unit and it's very simple to do.

Can someone please tell me the VO codes needed to do a SG Reset since I cannot connect. From what I have gathered it is 663 6nn and 6fl. Then after reset Bluetooth and usb will appear?

If I already have a mini stereo aux connection going to my center console but only a TCU, do I still need a MULF or can I just take out the existing stereo jack socket and swap it for a USB socket? My cars build date is 09/06

You'll need the MULF and coding, in addition to the socket and cable from the socket to the MULF, if I'm not mistaken.

Thanks. If I pick up a MULF off Ebay, is there any other coding that needs to be done besides enabling the USB?

What section and what is the exact coding for USB enable?

That I'm not sure on... I haven't done the retrofit, myself, but I've been reading and planning to do it.

Do you already have TCU w/ Bluetooth, or are you adding the MULF in order to get that, too...? I'd make sure the MULF you buy has the USB connector on it.

I do have a TCU w/BT. Just want to add the MULF for USB stick access. I take it not all MULFs are the same then?

I dont see anywhere in this thread it states what the exact coding is for USB only.

Gotcha. You're in the same boat as me, then.

I saw this thread, and specifically this post, which indicates that some MULFs offer USB functionality and some don't. That thread also shows 2 different connectors for the MULFs.

I'm not sure about the coding. I've managed to snag the cable and dl some software, but haven't had the time to try to code my own car.

Thanks for that link, I didnt know there was a difference. Would the MULF2 be replacing the TCU?

I assume it can, since it can replace the Bluetooth functionality. However, I think you'd loose the BMW Assist if you have it (I do). At least, that's what I was told by someone. I believe it's possible to wire both the TCU and MULF into the MOST loop together, but you have to do some rewiring of the pins into the MULF, IIRC.

I do have BMW Assist but dont have any use for it. Im wondering if the TCU would have to be coded out if it gets unplugged or if it will be fine and not send out any errors.

If you unplug the TCU totally, I WOULD code out the related options, though I'm not sure whether it's strictly necessary.

That said, it should be completely doable to wire them both in together. You'll have to do the MOST reconfiguration anyway.

I have successfully retrofitted a USB socket to my e90 and after changing the VO and then resetting RAD2 numerous times it eventually picked up the usb option in the professional radio.

problem now is that the audio cuts out 20 seconds after starting the car for about 5 seconds and then returns. I've had the radio professional recoded to latest version but it doesn't help. Any ideas anyone? There doesn't appear to be a separate amp in my car.

Please help, its driving me crazy every day.

The problem is that the techniques I'd use to debug that are a bit tricky, but I think I can boil it down to things you can check with only a multimeter.

First, your car definitely has an amp external to the headunit, it's in the trunk on the left side under the little plastic cover. The first thing I'd be suspicious of is whether the amp is turning off or resetting or something. There's a remote wire that goes from the headunit to the amp, telling it to turn on. I'd put a multimeter on that and get a friend to reproduce the problem while you watch the meter in the trunk. If that line goes from 12v (relative to the car chassis) to 0v while the audio cuts out, you know the problem is the headunit turning the amp off for some reason. If that remains live the duration of the cutout, I'd then put a constant sine wave into the system from an iPhone (download a signal generator app). That way you can put the multimeter on the signal lines feeding the amp in the trunk. on AC volts, if those go from something to nothing during the cutout, you know the headunit is cutting signal to the amp. Beyond that, or failing those two things, I'm not sure what I'd do next. I'd start there though.

IMPORTANT- NEW US Part Numbers

If you are looking for this mod, you need:

w/ MOST (Logic 7 / fiber optic bus)
65129350505

w/o MOST
65129350507

These are BRAND NEW part numbers due to audio quality issues with the old parts. (your dealer may not even have it in their system yet - but it can be ordered from BMW, ask them to add it).

$850$853$876$8S4$8TL$8TN$925$992*PM53-B080-EMOA-OSPS
As you can see, it has $6FL, $6NN and $663. I wonder if these's some simple mistake in my VO set.

I can successfully read the 'FSW_PSW.TRC' from 2URAD. It shows a lot of entries with 'hifi' in them like

...
and so on. These are just some examples, originally scattered across the file. There is a huge number of entries with 'hifi', so I won't post them all here.

However, a search for 'stereo' produces a small number of results, all of which are here

Code:

	e87_stereo
OUTPUT_GAIN_SUBWOOFERR
	e87_stereo
VOL_TEL_MAX
	stereo_mulf_e87
AUDIO-STANDARD
	stereo
There's also a number of "suspicious" entries like the following

Code:
AUDIO_SYSTEM_TOPAMP
	not_active
TOP_HIFI
	nicht_aktiv
EQUALIZER
	nicht_aktiv
(On the second thought, there's nothing suspicious about them: my system is not "top hifi".)

The internal menu in the radio still reports "Sound system: stereo" in the "Audio" sub-section.

Trying to do SG_CODIEREN on the 2URAD results in an error (same error many posters here already reported, see the attached picture). I'd appreciate any suggestions on what to try next.
ever have luck???
