Bluetooth enable TCU - question

Don't rely on a sticker. Look at the TCU build date. Anything listed as prior to March 2004 (listed on the sticker in DAY.MONTH.YEAR format, ie "USA 01.03.2004") simply won't work correctly. The Bluetooth hardware existed in the early build TCUs - hence the stickers and such. However, the hardware driving the system couldn't handle telematics and BT simultaneously. The early TCU bluetooth modules were hardware-disabled to ensure proper telematics remained operational. Unfortunately, that meant retrofits for those with TCUs earlier than March 2004.

My Ride: 545i
I just got my car back from the dealership and they gave me a really sketchy story about why they can't get my bluetooth to work.
I have an 04 545i with an 11/2003 build date. It has the right TCU and everything else, but they told me they couldn't reprogram the main computer to make it work because of it's build date.
Based on what you guys are saying that story doesn't hold water. Any thoughts on this??
What should I do next and who can I follow up on this with?????
Thx

LOL I just checked the TCU that installed in call and it has a manufacturing date of 2006. Sigh, I bought a TCU for nothing...oh well I can easily sell it here in Canada

My blue tooth now works after it was coded
Can't find a way how to mute the call though, and all of a sudden voice command works but says it cannot understand or sorry? and then system off.
Happy about Bluetooth though

Guys, I have 2003 E60, CCC... Haven't looked at TCU itself but I have Bluetooth option in iDrive Menu, I can pair it with the phone, however nothing else then pairing works. I also have inCar Phone. what does this mean? btw I suspect my TCU is broken (it unlocks my windows and drains my battery) so, still good to know.
