My Ride: Silver/Grey E60
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.

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