Although the Bluetooth Kits come with detailed step by step instructions for installing both the pairing button and eject box, the below quick pictorial guide will give you a good idea about the installation in the BMW X3. 

NOTE: Our Bluetooth Kits come with the latest Generation BMW ULF modules Available as shown in the BMW Compatibility matrix (and NOT the problematic first generation 84 21 954 552 others are selling,   Be careful on getting older ULF modules as some people have had difficulties and incompatibilities with the old first generation ULF modules.  Why use Our Bluetooth Solution?

All North American BMWs even without BMW phone currently are already prewired for phone.  You can verify by finding the Prewired for BMW Cellular phone in the trunk area.  Prewiring consists of wiring for all telephone equipment, plus coding for phone and voice recognition.  If your BMW is prewired for phone, and you install a new generation Bluetooth module, like we sell, it is unlikely that you will need to have your car coded.

Step 1) Lift up the lid on the arm rest to determine if you will need any additional trim pieces to complete your installation

To do a proper installation BMW X3 you will need the arm rest insert is similar to the one below shown as part number 5

If your X3 does not have this part you will need to get the trim piece from your local dealer.  Part number and details are below

P/N 51 16 3 401 961 ~$30 USA Right hand drive

P/N 51 16 3 402 727 ~30 UK Left hand drive

If your car is equipped with the proper trim piece or you have already purchased this piece, you can easily lift the rubber cover to expose the 4 torx screws.  Remove these four screws to expose the eject box connecting wires.  Plug your eject box wiring into these two connectors insert the eject box and screw the new trim piece back in place

Step 2) Verify that you have a microphone installed.  To remove the cover, gently pull down from the back with your fingers.  The cover comes down easily and snaps back into place.  If no mic is present, plug it into the three pin connector.  if you currently have BMW Assist your mic will already be installed

Step 3) Open the access cover by pressing the plastic release button just above the cover

Locate the BMW Assist module, OR the mounting bracket for the Assist module/Bluetooth module at the bottom of the access panel.  Remove the 4 8mm screws on each end of the assist module and replace with the Bluetooth ULF module

Remove the Pairing key sticker off the side of the ULF module and put in a safe place.  Plug the 54 pin connector on the ULF Control module, and the CREAM/Purple antenna wire to the other end of the ULF module.  PLEASE NOTE:  I have heard from some customers that they had TWO Cream colored antenna wires.  Make sure that you choose the Cream/Purple as shown in the below image.

The Bracket will have 3 mounting holes that are designed to fit the ULF module perfectly.  Ensure that you have the SES jumper plug installed - If you have BMW Assist, you will have the plug on the Blue wiring harness as shown below
