The below quick pictorial guide will give
you a good idea about installing Bluetooth in the BMW Z8.
NOTE: Our Bluetooth Kits come with the latest Generation BMW ULF
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

BMW has still not
made an official Bluetooth kit available, but a combined version of the
BMW E46 Bluetooth kit and the BMW E39 Bluetooth kit works perfectly,
when configured correctly.
I suspect there are a couple of reasons why BMW never made an official
Bluetooth kit available, with the primary reasons most likely being the
Z8 has no multifunctional steering wheel, and no proper location for
the Bluetooth pairing button. The creative solution for the pairing
button is to find a suitable home such as the passengers side ash tray.
The fortunate thing is that once you find a home for the pairing
button, you can use it to activate the voice control in the Bluetooth
module just as you would the steering wheel button.
As for the electrical connection a custom retrofit harness was made
specific to the Z8 that allows for a simple plug and play installation
of the Bluetooth module.
The Bluetooth system works for voice commands and pairing of the phone.
The Radio Nav display shows the phone information just like it is
displayed with the older phones. The Bluetooth phone phonebook is shown
as well as all the other features. All in All it was a success. I will
try to post operational images soon, although it operates, looks and
functions on the radio nav display in the same manner as the CPT-8000
phone. (or V-Series in the Euro)
Below are basic installation instructions on how to install a custom
configured Bluetooth system in your Z8.
Remove the cover of the drivers side storage compartment that stores
the CD Changer (same method as you would use to replace the CD changer)
Remove the three 10 mm nuts that hold the Original CPT8000 Module in
After Removing the CPT8000 phone module, disconnect the 25 pin
electrical plug to the module. This is the plug that the
Bluetooth module will attach to with the Bimmernav.com Z8 Bluetooth
Connect the 54 pin connector to one end of the ULF module and
the cream/purple colored Bluetooth antenna wire to
the the other end of the ULF module.
Mount the ULF module to the Bracket. You might need to modify
the holes slightly. Once you connect the Bluetooth antenna
wire and the 54 pin connector of Z8 Bluetooth retrofit harness to the
ULF module, connect the DB25 connectors together, as shown below the
ULF module in the image below.
Find a suitable location for the mounting of the Bluetooth antenna,
exact placement is not crucial as anywhere inside compartment will be

pairing button in a suitable location. The passengers side
ash tray is a great option as it is stealth, easy access and very
functional. Plus, the best idea about using the ash
tray is that it is a cheap replacement if you destroy it during the
modification. You can use the

Below is a good photo with descriptions of each of the plugs located
under the console. NOTE: You should NOT typically need to
remove the console to access the connectors.
New Ash tray with pairing button installed
Pairing button wiring run. If doing the ash tray mounting of the
pairing button, you will only have a short route to run wiring from the
ash tray to the location of the 18 pin connector. The 18 pin
connector can be found by following the CPT8000 curly cord
wire under the carpet in the tunnel. Disconnect the 18 pin
connector for the older phone system, and connect the new connector for
the pairing button. You can then remove the old phone curly
Route the wires in
the kit to the location of choice for the pairing button
The Passengers side
ash tray mounting location is a perfect spot because of it's stealth
location. You will only see the BMW Pairing button, when the
ash tray panel is open. Plus there will be no noticeable
indication that you have any non-factory Z8 part in your car aside from
the BMW button in the ashtray. Although the functional
difference will be that you now have a working phone system in the car
using your Bluetooth phone even while the phone is still in your
pocket! In addition, the kit consists of BMW factory parts
and equipment and it functions exactly as your original CPT8000 phone
operates and functions.
You can pair upto 4
phones to the BMW System at any time and the Bluetooth function will
automatically detect your phone when you start the car. Once
you decide to make a phone call, you can use the phone directory on the
Radio navigation display or use the pairing button to activate voice
If you do not
have a microphone, remove the overhead mic cover and install the
microphone. The updated microphone is also an option as it
When mounting the microphone, make sure that you have the ARROW on the
microphone pointing forward
Once you have
tested your system, you can put everything back together the opposite
of how you took it apart
Once you have
installed your Bluetooth system, Operation of the unit is the same as
other BMWs. To pair the phone, press and hold the pairing
button with the ignition off. With the button still held
down, turn the key to the first position. After 3 seconds let
go of the button and the red light above the phone icon will flash to
indicate you are in pairing mode. Use your Bluetooth phone to
initiate pairing and input the pairing code passkey from the Bluetooth
module into the phone.
Once you have
paired your phone, turn the ignition off to complete the
process. Once the process has been completed, you will be
able to use the Telephone option on the Radio Display to operate the
system. For voice commands, press and hold the pairing button
and speak the commands such as dial number, dial name and other voice
