Hello everyone. I have a 2004 525i with a 05/2004 build date. Do I have the TCU that can just be activated by BMW for bluetooth or do I have to replace it? Thanks guys.

 

I have a 05/2004 build 530i and all i needed was the software update to activate the Bluetooth function so i would assume that is all you need

 

Yep, that's all you need. Member SMG353 just got the update on his '04 545 and he now has Bluetooth on his car.

 

Thanks. I'll hook it up next week. After that i'll post an update of how my girlfriend and I broke up beacuse she heard a conversation in the car she wasn't supposed to hear. =)

 

How much is the activation?

 

mann i have a 06/04. i thought you had to have the 09/04 build or later to get it. my tcu does have a bluetooth logo.

 

Adding to the thread, last week I posted that my 2004 545i build date 07/04 had the BT enabled , software only. No TCu needed.
Just some more info.

 

x2 I would like to know that too if anyone has the info?

 

I just called my dealer I have a 4/04 build 530i and they said i needed CPT 9000 is this true??? Or is it just the software update?

 

This has been discussed many times on this forum. For those that have not been able to use the search function to find the Service Bulletin that explains this in detail, here it is. This should answer most of the above questions.
