Thanks!

Glad to have helped!

I checked the reconfigured blue connector for the MULF2, everything is exactly as the guide says.

I also checked for the mic, even though I know its there because voice commands worked previously, all is well there.

Is there anything else that I could be missing to get the mic working?

Thanks in advance to anyone offering advice!

You could try wiring it back the way it was, but also pop the trunk and verify the wires exist in the MULF header - I've seen cases where they don't, and we just ran a new cable.

I tried to move the wires behind the glovebox to their original locations, no go.

When you say verify the wires exist in the MULF header, I moved the mic wires from the white connector that was plugged in to the MULF originally to the blue connector (pins 1,19,21). The sheath looks like the same one I was using behind the glovebox.

Running a new cable wouldn't be a terrible option if I just have to run it from the MULF to the mic in the headliner. I saw your post somewhere else about building a cable, could you provide any details on the install / building of the cable?

Thanks again for your help!

I'm not sure what you mean by white and blue connector, there's only one large harness that plugs into your MULF, right? Should be pins 1/19/21 on that.

Running a new cable is a bit of a PITA, but not the worst. I can do it in 30m or so now that I've done it a few times. You need to pull down the headliner (two screws in the sun visors), A pillar trim (one screw and some clips), fish the cable through the dash (easy with a hangar or some steel wire), left side driver footwell trim (one screw on the hood release), driver door scuff plate (just some clips), B pillar trim (clips), back driver's side scuff plate (clips), then some seat trim around the C pillar (remove the back seat, remove the seat back [2 big torx] remove the trim [clips]). Just zip tie to the existing wiring harness.

The cable itself is pretty straightforward - I've been making them by buying some shielded twisted pair 24ga wire on ebay, the Mic side connector can be made with 3 positions of breakaway .1" female pin header and some shrink tube, then on the other end crimp on 3 pin contacts. The part is TE Connectivity 963726-1, I got them from Mouser but it looks like they're not distributing them anymore, Newark has them cheap http://www.newark.com/te-connectivit...0120425_buyNow

I've also made cables for a bunch of people if you don't want to spend the time, though I charge more for the time and shipping. PM me if you want to go that route.

Have you already got the bluetooth antenna taken care of?

[AWD Addict]

Does anyone know of a way I can get the coding done for this in Boston?

[rrlamichhane]

Can I pay someone to do all this? I hate messing around with cars, and I want integrated bluetooth music in my 2008 335ic.

You might want to post in the regional subforum. If you were in LA, I'd certainly be willing to help :P

On my TCU connector, I have the yellow and black wires in pins 1 and 19 but I have a grey wire on pin 21 instead of clear one like in the DIY. The three wires are also in a black sheath instead of the clear one like the OP has. Anyone else come across something like this?

Also, I do not have voice command already so do I need to repin the connectors at the glovebox?


*update:* Turns out the yellow, black, and grey wire are for the mic. Had to repin the connector at the glovebox and the mic now works for the bluetooth. I tried adding VO $620 for voice control but that just disables the voice command for bluetooth as well... Not sure what's going on there.

[freak1]

Just wondering what this unused connectors would be underneath my '06 330i E90 Sports Package center console. Is it prewired for some additional functions?
Btw, I have voice control, bluetooth phone with idrive and navigation from factory. Just looking for options to see if I can upgrade to usb playback.
Any help is greatly appreciated.
Thank you

[jezzy]

This is for a iPod/iPhone cradle that fits into the arm rest. You will need a tcu in the trunk for usb. Or go all out and get a combox

Thank you for the information. Stumbled on the web and trying to figure out if I can just swap ULF with combox? Any link or hardware recommenation would be awesome. Btw, I don't want to do CCC to CIC retrofit. Just usb and mp3 playback will work for me.
Thanks again

[freak1]

Bump
My e90 330i build date is 2005/07. Is it possible to add mulf2 high svs to get usb playback feature? I would apprecite information. Btw, bimmertech had this option but its kinda expensive.

Hi all,

My E92 (2007) came with the options below, but despite this I can't find the fakra antenna wire under the driver's side footrest to do the bluetooth retrofit (I just bought a combox telematics module)
I do have three wires + a MOST connector in my trunk, but no MULF or TCU.

S620A - Voice control
S640A - Preparation f tel.installation universal
S693A - Preparation BMW satellite radio

Can I just purchase the BT antenna module and leave it in the trunk, connected to the combox module?
Or, else what's the best route to take to do this retrofit.

I also want to mention that my car has the CIC retrofit also.

[dsantos08]

If I have BMW assist do I still have to follow all these steps regarding rewiring the ULF and TCU in the trunk?

Or can I just connect the bluetooth antenna straight to the ULF in the trunk with a cable I bought on ebay. Then just code it and have it work?

Or will the microphone and voice assist not work this way unless I do all the wiring modifications as listed by the OP?

[alexwhittemore]

You can test now without the antenna. You might need the phone in the back seat, but it should at least connect. That way you can do only the coding and figure out exactly what hardware work you need to do before you even start.

That said, I think it'll go like this: code it. Everything looks good, you paid your phone and make a test call. You can hear them, they can't hear you. Then you need to figure out if you can re-pin the mic, or if you need to run a new wire.

I can't even pair my phone right now. When I hit menu on the radio, there isn't even a TEL icon. I took it to a shop last night and they said the auto logic is pulling an error code that it can't communicate with the radio unit so they are guessing it might of been replaced? They couldn't tell me for sure what was going on. But here is a pic of my radio when I hit menu.

[alexwhittemore]

That's normal. You just need to code in $644 and do an sg_reset job at the menu before you've selected a specific module. That'll reset everything and the tel option and menu items will appear.

[alexwhittemore]

Search sg_reset and you should find a more detailed procedure.

So I called BMW genius and they said my car definitely has BT installed. So I unscrewed the panel under the drivers side and there is actually a bluetooth antenna installed and connected by a wire. However on the panel, a square piece was already hanging out before I took it off so I popped it back in (I'm guessing this is the MOST connector?). I'm wondering if this hanging piece is a sign that the BT antenna was tampered with?

Anyways the antenna is installed and wired but somehow the TEL option doesn't pop up in the menu function of my radio. What is going on? Weird.

Also when I took the car to get scanned with autologic, they said it couldnt communicate to the radio. So I'm guessing this might have something to do with the BT not working?

EDIT (11/10): I just spoke with the previous owner and he confirmed that bluetooth worked and he used it all the time. I bought the car certified from a dealership. And I'm trying to figure out what went wrong between when he traded it in and when I bought it? Could the dealer have reset the codes on the car and in effect messed up the bluetooth functionality? Or maybe one of the technicians swapped out the radio head unit that was mated to the BT antenna? I'm going crazy trying to figure this thing out.

It looks like I have a combox installed with the Bluetooth antenna wired to it. This is so weird. Is there a chance the dealer swapped out the original radio and it's not compatible with my combox which is why the BT isn't working. But my iPhone plays just fine with the usb connection so I know the combox is working.

[alexwhittemore]

So your car is pre-wired for phone, which I suspect means a production date pre- September 2009. That means all you need to do is code 644, possibly install a mic (the wiring will be there). You code this option into CAS and FRM, you don't need to be able to communicate with the 2RAD module.

i have same isue , and i dont know what to do , i had ccc professional, i retrofited to cic and now doesnt work bluetooth(mulf2) maybe someone know what to do? ( my new car bmw e60 2008

[ptpending]

you need to code CIC with bluetooth option

[thethief1]

Great job, I need another version of this DIY. I am going to create a new topic. I'll appreciate your help.
