Best I can tell, that harness is ONLY for USB, part of which includes supporting the MULF, which overlaps with phone prep but is not phone prep in and of itself.

I only looked quickly, but the harness in the kit does not include the cable running to the Mic nor antenna, and thus is not phone prep.

I see your point, sorry my car has factory bluetooth so i wasn't thinking of these problems!

May be you just need 2 & 3 here as well: http://bmwfans.info/parts/catalog/E9..._free_kit_uni/

Actually ignore this it seams to be a universal kit.

This looks like what you need though, second kit ending 247, says for cars without telephone prep! http://bmwfans.info/parts/catalog/E9...cil_bluetooth/

[alexwhittemore]

Looks like maybe, but without any detail there's nothing on that harness that looks like the mic connector. I honestly don't know.

It only cost me $20ish for cable and pins, the $60 mic, and a bunch of time to install.

For anyone attempting this retrofit for Bluetooth with the MULF2 High module. Meaning your car came with just S640A option. 2 things to note.

1. The mulf2 high module is used for USB as well; therefore when it comes to coding, add both S644 and $6fl to VO. Even if you do not need USB (Yet). The 6fl option tells NCS Expert that you have mulf2 high module and will call up the appropriate files to perform a reset for the mulf2 unit. i.e no errors.
   
2. Your S640A (Phone prep) means the car is prewired for a TCU not the MULF2 unit. Rewiring is needed in the fuse box area for the microphone to work.

This worked in the blink of an eye for me. Radio is 2URAD as well.

Thanks to everyone who helped on this retrofit. alexwhittemore Thank you sir!

I decided against this route and instead I am fitting the newer professional HU with usb and bt built in, as explained in this thread: http://www.e90post.com/forums/showthread.php?t=687463

It is much easier, quicker, better and cheaper than adding the mulf2 and retrofit kit, especially as you can sell the old HU! and mulf if you had one!

To be honest it is easier for an install but this HU you speak of is much harder to find and is more expensive than a MULF2 retrofit. Head unit costs ~$500 MULF can be had for $200, with other bits put it at around 350 total. Then there is no garantee that you could sell an old HU either as that demand is not here..

[gazosnic]

For the guys who did this retrofit from the phone prep wires, can you please explain which wires need to be repinned from the white connector to the blue? I would GREATLY appreciate it if someone can please list this. Cant find a clear answer on this anywhere.

Mic Wire from Guitar center for the win. My junk yard pull with the upgraded SOS button was only 43 dollars + mic. BMW Junk yard parts are cheap cheap cheap

okay...my brain is smoking after reading thread after thread on this.

All I want to do is add Bluetooth to my car. I have the SA640 option installed. If I add the Mulf2 to the car, do I need any other parts with it (like BT components) to get it to work? Im not interested in the USB function as I am happy with my Aux cable input for my iPhone music.

I understand coding will be necessary too.

A simple, logical answer would be greatly appreciated.

Thanks!

I'm pretty sure the following is correct, but please verify:
you have $640, and you're pre-LCI, meaning you're pre-wired for phone.
You have NO USB jack in the armrest.
You have visually verified that you have no mulf under the trunk liner

I believe you will need only a MULF, probably no coding. You MAY need a microphone, and you MAY need a bluetooth antenna, as I think both are left out of the prewiring, but I'm not quite certain. The Mic wire and antenna cable should both be installed with the prewired harness.

I have an '08 E92 with iDrive and the following features:

S609A Navigation Professional
S620A Voice Control
S640A Preparation f tel.installation univesral

I bought the MULF2 unit that ThumperX used in this installation. I also bought the other related parts, but my question relates to the MOST cables behind the rear seat. I opened the area up and saw the 2 connectors. In the retrofit guide, it shows one connector with 3 wires and one connector with 1 wire.

However in my car, I have the one connector with 3 wires, but the other connector has 2 wires. So my question is, do I still do the swap of those wires, and which wires do I swap? I can provide photos and more details if necessary. Thanks

Even with the pictures, I probably can't tell you, but what I CAN tell you are three things that should help you figure it out.

1) The MOST bus is a ring topology. Each controller on it has an input and an output. Imagine I have three devices on it, the MULF, the headunit, and the Logic7 amplifier. The bus might be set up such that the MULF output goes to the headunit input, then the headunit output to the L7 input, then the L7 output to the MULF input. In this way, if the MULF wants to send a message to the headunit, it says "Hey headunit, X." The headunit is the first to receive it, so it reads it and takes it off the bus. If the headunit wants to reply to the MULf, it puts a message out on the bus saying "Hey MULF, Y." The L7 amp is the first to get it, but it recognizes the message is not for it, so it just forwards it. Then the MULF receives it.

2) order doesn't matter. All this means is that every output must be matched to an input, but as long as they're all matched thusly, it'll work. If you find the lead that's the MULF output, you can plug that into the block there directly opposite the headunit input and away you go.

3) With the car turned on, the outputs will be lit up. For example, in that block behind the seat bolster, there are a couple green fibers coming from the trunk area - those will both be the MULF. There'll be a couple coming from up front, those'll be the headunit. Of the two from the MULF, one will be lit up read and one won't be. The red one is the output, and the dark one is the input!

The only other caveat is that there's a diagnostic port in the pedal trim that's basically a MOST connector, but with a cap on it that just optically shorts input to output. I THINK that's always wired in series with the headunit since it'd be silly to run extra fiber back to the back seat, but I'm not certain that's true.

Alright, thanks, I guess that does help a bit, I just need to wrap my head around it. I basically took pin 3 from the connector with the 3 fibers and swapped it with pin 1 on the connector with 2 wires, and I lost all sound in the vehicle (radio, nav, voice control etc), so clearly that's not it. Then I swapped pin 3 from the 3 fiber connector to pin 2 from the 2 fiber connector. Same result, so I'm assuming that I should just leave the alone.

Thumperx.

I am in the process of completing my retrofit, pretty much the same as yours, minus the iPhone cradle and use hub.

How did you route the aux output wires to the ULF. I understand that pins 1,2,3,4 go to pins 23,22,5,4 of the ULF, but I can't find any write up on a BMW OEM wiring set used for this purpose. So this leads me to believe a wiring harness was made. Is that what you had to do? If so, what parts did you use?

Wow OK this thread has done my head in.

I have a 2007 335i. I'm wanting to install USB (I currently have none, not even in the glove box)

According to my VO I have $640 so im thinking that all I need is a MULF as there is nothing in the boot just a taped up loom, and the Retrofit kit USB/audio interface kit listed in the install PDF.

A local shop quoted $1600 to install the 6FL kit.

The car is a Japanese import and I just today had the radio reset so that it will work here in NZ.

Cheapest & easiest way to retrofit USB is to buy a head unit from a 2010+ car with factory USB! You'll also need a cable and USB socket, then just add 6FL to VO and change car build date in VO to 2011 (say 0711 for example)

I did this on my 2007 E90 with a used head unit i managed to source for £300!

Hi,

I have the below options in my 2009 335ix (E92)
6FL USB-/AUDIO INTERFACE
609 NAVIGATION SYSTEM PROFESSIONAL
639 COMPLETE PREP. CELLULAR PHONE USA/CDN

I want to install the telephone cradle option in the armrest, so my question is that something straight forward, I just buy the part and install it by plugging it in or its more involved.

Any info on this greatly appreciated

Thanks

What reason(s) do you want the phone cradle for?

Can't you do that via the USB socket?

[ricapctba]

Hello,

I purchased one BMW e90 last year. And i want to use USB. My BMW have Professional Sound Harman/Kardon and dont have USB, only AUX. Then i bougth one MULF with USB (mini cooper(picture)), i plugged, but not working USB and AUX, only bluetooth. In the radio, have USB now(picture), but not work, not read pen drive.

Can you help me?

tks
