My Ride: 2004 325i
nevermind I did some searching and found a BMW TSB explaining things...

For E46/E83/E85/E53 vehicles produced
between 3/2004 and 8/2004, are equipped with a
TCU that does not support Bluetooth. On these
vehicles the TCU can be replaced at the
customer's expense with a 2005 MY TCU.
Cradles may not be added to these vehicles
because of wiring incompatibility.
***56256;***56442; Please disregard the Owner's Manual insert,
shown to the left, indicating Bluetooth
functionality. The hardware in these vehicles
will not work correctly.


When I push the SOS button shouldn't this activate assist and send me to an automated message telling me that my subscription is expired? Also if I wanted bluetooth I would only need the bluteooth ULF or a new bluetooth TCU and replace it with the assist TCU to make it work as I understand it I should already have the bluetooth antenna installed
