Another dope who doesn't know if he has Bluetooth or not...help, please. MY2004

Hi, All,

I've got ( I think ) an 08/04 build X5. I have Premium Package, BMW Assist and, from what I can tell, all the Bluetooth hardware. I have the card with the PIN and I have also verified the ULF in the trunk ( also with Bluetooth PIN on it), complete with phone AND Bluetooth antennas going into it.

My phone is a Motorola V710 (US Cellular, not the disabled Verizon one ).

I've seen the bulletin stating the some late '04s may have had the card included, but I appear to have EVERYTHING.

I checked IFlyX5's excellent writeup:

http://www.xoutpost.com/articles.php?...icle&artid=190

Basically everything looks just like his end result...right down to the mounting of the Bluetooth antenna and the location of the ULF.

I have NOT been able to get the phone to pair, despite trying multiple processes.

Is the ULF the same as the TCU? Do I need to replace it with a 2005 version? And why the heck is it there ( complete with antenna ) if it doesn't work in '04s...anyone know?

Thanks,

--Will

Will: have you considered taking your X5 to the dealer in Westbrook to see if they need to activate the Bluetooth via the vehicle programming?

Will - I suspect that the TCU (aka the ULF) in your 2004 will not support Bluetooth. The reason it is there is to provide Assist to the vehicle (hence the antenna connections). You can replace that TCU with a 2005 unit (you'll also need to have the vehicle recoded) to get BT and Assist.

Thanks, guys. I will be going to the dealer tomorrow. Alas, they are totally clueless and believe that I "do" have functional Bluetooth and just don't know how to start the pairing process. I have a feeling I am in for a long morning as they struggle to activate my non-functional Bluetooth and then are clueless as to locate the right part to retrofit to bring it up to '05 standards.

I bought the car in Peabody, so I will try to diagnose the "cure" over the phone with them first. The dealer in Westbrook has historically been completely clueless regarding all makes and models, but I will undoubtedly end up there for service.

Late builld '04 BT

I have been told that there were some 8/04 build '04's (in 9/04 they started building '05's) that actually were originally spec'ed with the -993 Combo Assist/BT TCU, but that the cars were not coded properly to recognize the bluetooth. If the TCU in your car ends in -993, you should be able to have it activated by re-coding. If it does not, you will need to replace the TCU with a combo unit as UCREW suggests, and the newest version of that piece is the -114 version. Good luck, and let us know what you have

Interesting...

My part number appears to be 84 11 695 221 801, so I guess I'm out of luck. The date on it appears to be 8/10/2004.

New question. The -114 part number is apparently going for $720 these days...ouch. I assume that this is the combo Bluetooth/BMW Assist '05 part.

Oddly enough, the stealer says I need part # 84 21 6 934 552, which only retails for $435. I'm not planning on coughing up the ~$250/year for Assist once mine runs out...is there any reason not to get the cheaper part?

If you are not planning to use Assist then getting the Visteon module should work just fine. The -552 is a bit old, as it's the first generation module and BMW is now up to the seventh generation (see http://www.xoutpost.com/articles.php?...icle&artid=171 for the version history). If you can, try finding one a bit newer in vintage.

You can find additional info on this conversion at http://www.xoutpost.com/articles.php?...ticle&artid=23

Good Luck!!

Thanks, UCrew,

Any reason to not just go ahead and get the Advanced Autovation one for $510?

I believe you will find that the ULF's from Advanced Autovation are more recent then the ones that you can typically pick up from your local dealer, which is what you want.
