Hey guys, I can't figure this out or find any relevant info on the forum.

I have this "phone" button and R/T on my steering wheel.
Can I connect my BB Curve with BMW system?

I tried pairing up my BB Curve with my car, but nothing worked.

Sorry if this is lame question, if there is similar topic on this forum, please post the link. Thank you !

:search:

almost all e46's come with those deceiving buttons. a few quick ways to check is to pull down the panel where the reading lights are in the headliner and see if theres a mic. or, go in the trunk and pull the carpet back on the left side (much easier than it sounds) and see if theres anything going on in there (any lil metal boxes mounted horizontally with wires attached [TCU or ULF])

if it has assist (sharkfin), you can swap out the TCU with a newer one from Tischer ($400). i just did it a few weeks ago, took about 10 minutes and works flawlessly.
Good luck on searching those key words I'm interested in.

I know I have a mic. because when I was playing around with my rear view mirror I pressed SOS button (next to assistance button) and it told me I'm not subscribed to the BMW service and to end this call say "Good Bye".

So how do I connect to existing system? Does it have Bluetooth or I need to buy newer TCU?

the phone button i believe was first used in conjunction with the factory wired phone, kinda like the in-car phone on the older e38 7 series. then it became a button for bluetooth. to sync your crackberry you need the blutetooth kit, pricey IMO, but i believe it allows for some neat features like phonebook access, etc. if you just want the button to answer/end a call and use the speakers as a speakerphone, there are cheaper solutions out there that require less installation work and function just as well.
Ok, so I would have to buy the BT kit in order to synch. my BB with it? I thought that since there are those rear view mirror buttons and "car talks to me" when I press SOS or Assistance button it had some kind of built in BT, but I guess it doesn't.

Thank you for your input guys.

Luke, I have the same question...what does that button allow me to do?
Well, as you see opinions are different.

I will do some more research on this once I find some free time and will post back with results. It is hard to believe that there is a button on the steering wheel that doesn't do anything unless you buy extra module.

From the link posted above:

I found out some info about "pair up" button which I don't have, weird because my car is 2005 and according to discussion in that topic the car should be equipped with TCU :/ thus it should have "pair up" button under the arm rest ? :eeps:

I will check out my trunk for TCU later on.

You have an SOS button, meaning you should have Assist, meaning you should have a sharkfin, meaning you should have a TCU, meaning the mic should be in the headliner grille thing by the reading lights, meaning you're missing something. Yes, you have a 2005, but I think at that point it MAY depend on the build date. BMW was generous in 2005 and said, ok cool you sprung for the Assist, here's some bluetooth while you're at.

The "pairing button" that you see on other posts is for the ULF (much more cashmonies) and for ppl w/o Assist. It goes where the coin tray is under the armrest, or under the armrest like most ppl do because you only need it for the initial pairing.

Mine also came WITH a card that said BT passkey. BMW acknowledged that they messed up by sending it, since they didnt equip it with the unit (d'oh!)

That being said, let us know what you find in your trunk, and we'll take it from there ;)
Thanks man !!
With the information you provided I went into my car again during the lunch break ;)

Shark fin = check
SOS button = check
Assistance = check
Mic. = check
2005 model = check

So I started up the car again and tried to search for devices using my BB Curve. No good, so I went into my BB options and made my device discoverable (duh) and ta da - found BMW audio device.

I started digging in my trunk (left side) but gave up since people who were passing by were looking at me really weird ;)

All I need now is the pass key. Do you think I can get it by calling BMW dealer or do I really have to remove my trunk cushion to get to TCU?

Edit 1: So I called BMW and this lady told me it is going to be 0000 or 1234, WTF? :D I guess she has no clue what the hell is TCU. Thanks again guys for all the input. I will look for TCU when I get home.

Edit 2: Another dealer; bring the car to the service, we will connect it to the computer and tell you the pass key. I didn't even ask for how much ;)

OK, so I got this figured out and here are the steps for E46 Sedan equipped with BT.

Before you start remove everything from the trunk, that includes the trunk mat and the spare wheel cover, then proceed further.

1. Remove left taillight cover and put it on the side
2. Unscrew and remove top, left plastic nut from the back cushion (there is two pieces there, screw and plastic mounting plate so don't loose it)
3. Pull out plastic pin with flat nose screwdriver or long nose pliers.
4. The same as number 3
5. Pull the cushion up
6. Pull the cushion away

Your TCU is sitting on the top of the plastic shelf.
You can easily read PK (Pass Key) code from the sticker.

To synch. your phone with BMW BT.

1. Make sure your phone is discoverable
2. Start your car
3. Search for devices using your phone
4. You will find BMW audio device, connect to it
5. Type in the PK you found on your TCU sticker located in the trunk
6. Enjoy

Ha ha, well, I really don't want to remove this again, but I will be doing clear corners, around June 30th and will be more than happy to check what is on that sticker, detach the wire and take more pics of its connector so you can compare it with yours. If you don't find the answers by that time, just let me know.

However I have never been able to discover bluetooth in my ride. I guess they weren't feeling so generous with the 2004 models. Did anyone else with a 2004 find out they have blue-tooth?
Make sure your phone is discoverable and search for BT devices right after you start the car.
