Bluetooth help needed on 2005 325xi, I'm so confused

If anyone can point me in right direction I would sure appreciate it.
My 2005 325xi has a manufacture date of 08/2004, which after reading online for hours upon hours I've found is the transition month when they started putting bluetooth in these things. My info from VIN says "HANDY USA/CDN Preparation f mobile phone cpl. USA/CDN". The car has a microphone by dome lights and has voice dial button on steering wheel, and when I press it it says no #'s stored. So I'm wondering if there is any way to determine if this has it or not. I tried the obvious searching for device with my Iphine, but it just keeps searching. So I'm wondering if it could have it and just not be activated? The car has a iphone cord running from glove box, that I can hook up ipod to and play, but Illinois just started hands free phone device while driving law, and I have to get this sorted out for the wife.

Anyways, if it doesn't what would be the most cost effective way to get something in there? Can I somehow make use of the existing microphone.

Sorryto ask this as I know from reading this has been discussed at length, but that 08/2004 MFR date has me stumped, as everything I read says thats exactly when they started putting them in.

Thanks in advance again gents.

Might consider something like this?

http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

Supports A2DP so no connection required between phone and car to stream audio from phone and speaker phone uses cars speakers to hear incoming callers.

The nice thing about OE Bluetooth is if you are listening to the radio or it is off, the phone will still ring in, this is not the case with this type of adapter that the Aux would need to be selected/functioning.

I recall the BT can be turned on and off with software on the car.

If you press and hold the steering wheel button and get a response that there are no numbers stored, then you likely have an OE BT module?

You should check the trunk to verify and find the module and see if the module has the passcode on a label.

FYI, the car will not likely have a pairing button as well. The OE BT info is all garbage, out of date and incorrect.

Software likely NavCoder or BMW Scanner 1.4.0??? can typical read the BT Passcode electronically and enable and disable the OE BT as I recall.

Yes Jfoj is right.

When I picked up my 2005 330i last year, I couldn't get the BT to work as described and all documentation would only get me so far, so I researched it for months. My phone would find the car. It should be BMWXXXXXX which is the last 6 digits of your VIN. If that doesn't work you might not have a module installed. Are you sure you have a mic in the ceiling? You would need to remove the panel. My car doesn't have voice control.

If you open the trunk, what round medallions do you have on the underside of the lid?
There is no pairing button, so you would need to know the code from documentation. But I ended up purchasing the BMW Scanner 1.4, and I was able to pair my phone. Then I could use the RT button to scroll through the address book and hit the call button on the steering wheel to place and disconnect a call. Once paired the car and phone will sync within 30seconds.

Here is some of the documentation and links I've used......

I have this in my car and it works great. cclear sound and the music quality while streaming is excellent. my only two gripes would be the wires and the fact that you cant shut the ashtray cover with it plugged in. another nice thing is you gain a usb power slot for charging.

If it's like mine, the car's bluetooth tries to pair as soon as you turn the car on. You need to know the code for your car. Since the code was not supplied to me from the previous owner I had to read it off the unit in the trunk. Had to unbolt, remove and flip it over to read it.

After that it was a simple process of turning on the ignition to accessory and go directly into my phone's BT setup and enter that code when it found the BMW.

Also some phones you have to specifically tell it to continue to or remember to pair with a specific device, otherwise you will have to repair each time.

Contrary to belief the passcode has nothing to do with the VIN and even the Bluetooth broadcast ID may not have anything to do with the VIN.

You can change both the broadcast ID and pairing PIN number in software as well as enable and disable the BT feature.

If you have a later model car with SOS then it is likely the car has BT, either a ULF or TCM. I think the SOS cars had the ULF?

If you hold down the talk button on the steering wheel and get voice command prompts this is usually promising.

Thanks for the help guys!! This car has me baffled inregard to this. I looked everywhere for a pairing switch no luck. I pulled the cover off the microphone and there is indeed one in there, there is a shark fin antenna on it(if that matters). I then went to the trunk and looked for that box, but I dont see one.
So, I'm thinking they just went through the motions on this one, put everything in place, and then said mehhhhh, qutin time.

OK, one last hail o mary...........
I found a few posts here of owners with a 2005 E46 with all the things I mentioned, steering wheel control, microphone and box under panel by dome light, and a BT code in with owners manual, that couldnt get phone to sync (iphone just keeps searching to no avail). Unfortunately the threads are several years old, and they dead ended before a result was given. I tried sending those members a pm, but they havent been on in years, so I doubt it will reach them.

I found alot of other threads that say even with the 08/2004 mfr date if I have the code card, I have it, but yet again, I found a few others with exact MNF date, that had similar problem.

If by any chance someone sees this and recalls a cure, PLEASE let me know.
Thank you!!!!!!

wapner, I feel your pain. Been dealing with this off and on with the xi ever since we purchased it a couple of years ago. And you'll never guess what the build date is .... wait for it ... 8/04.

This issue even frustrated a SA at the dealership last summer. He said the car definately had it. He activated the "assist" feature, saw the microphone, pass key, etc., etc.

We left it off with him going to check with some people in the know on this issue and he'd get back to me. Never heard from him.

I gave up until I saw this thread. I think I'll contact BMWNA and see what they have to say. If I ever hear back I'll be sure to update this thread.

Good luck to both of us I guess.

Thanks for replying!! I really thought I was going crazy with this! So that is now 4 confirmed people(2 of dead end threads from several years ago), yourself and me all with 08/2004 builds with identical problem. Yeah, please let me know if you find anything out. I was gonna swing in BMW by me tomorrow, and ask, but these are the same Einsteins that convinced me my car didnt have a fuel filter 2 weeks ago when I went in to buy one, so I doubt they'll be of any help on this.

I'll get the old "hey why not just take a spin in the new 2014!!?"

Skip BMW Dealership and BMW NA, they will waste your time.

You either locate the ULF/TCU in the trunk and see if it has a Bluetooth Passcode on it AND get BMW Scanner 1.4.0 and see if you can actually communicate with the module in the car.

What I will tell you is these ULF/TCU modules are not the most reliable things.

When they start having problems, you have to pull 2 fuses and basically reboot the unit.

Also this may be a rumor, but I have heard that the ULF/TCU may only be able to handle a few phones and at some point you have to use the software to purge the paired phones from the module.

With either NavCoder or BMW Scanner 1.4.0 you do not really need to do anything other connect the cable to the car and communicate with the ULF/TCU.

But it is wise to make sure the module is actually in the car, because you could have a module that is in the car, failed or part of the module has failed and you may or may not be able to communicate with the module using software.

ULF is in a hard cast aluminum chassis that has the BMW Assist phone module it in, the

ULF - https://www.google.com/search?q=bmw+...87%3B800%3B370

TCU imodule is in a stamped sheet metal chassis that is basically the same size as the ULF module.

Place your order now for BMW Scanner 1.4.0.

Trust me, you WILL need it.

BMW NA will not offer any solution, they will direct you to your local dealer.

It is amazing how little that people in the dealer network know about these cars.

Yes it is difficult due to the fact that there were a lot of options and the info about the Bluetooth is all very out of date, inaccurate and misleading.

This what u need to do. Get the card that has the bluetooth passcode in it. Get in your car and put key to accessory position (DO NOT TURN ON CAR) go to your phone settings and search for bluetooth devices. While your phone is searching.. Hold the button on the steering wheel with the face speaking symbol. Your car should then show up on your phone. Enter passcode and ure done. Lmk if it works. I had my car for a yr and always thought i didnt have it but i did.. Figured it out 2 months ago.

Do not even need to hold any buttons, at least this is the case with the ULF as it goes into pairing mode for about 2 minutes every time the ignition is turned on with the later modules.

BUT, everyone needs to also understand not FULLY knowing the history of their car, someone could have removed the module, swapped the module or the module may have just failed at one point.

Pretty easy to sniff out any Bluetooth signal being transmitted with your phone.

Assume the OP has already tried this?

Yeah I already tried that about 100 times, no love. I think jfoj nailed it when he mentioned it reached its max amount of phones. I am not original owner, and my best guess at this point would be, it has max phones stored. So I will order that tool he mentioned and get in there and see if I can clear phone history. That makes sense.
Thank you again!!!

Pull the radio fuses for 1 minute.

I do not recall the exact numbers, I think maybe #7 and #25??
