    BMW Bluetooth fully integrated in Z8

    The below quick pictorial guide will give you a good idea about installing Bluetooth in the BMW Z8.

    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 place.

    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 Z8 Bluetooth adapter harness

    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 perfect.

    Mount the Bluetooth 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
    Pairing button cutout template for the cutout hole

    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 Bluetooth module. It can be easily snaked under the trim pieces if you remove the cover of the CPT8000 compartment. The compartment is really obvious on how it comes up.

    The wires are then connected to the proper location on the adapter harness

    Finished Ashtray location

    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 dialing.

    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 improves performance.

    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 control commands.

    Here is a customer who took the bluetooth kit and got creative.

    They have finished the installation by adding in a RAZR snap in adapter in place of the original CPT8000 phone system

    We took a standard Z8 Bluetooth kit. Using the electronics from an Eject box a Razr Snap in adapter was mounted where the standard phone system is typically installed

    Razr in Action

    RAZR mounted

    New mounting screws that rarz snap in was mounted to the console trim piece

    The Eject box circuit board was removed and mounted in the console trim piece (easily replaceable part if necessary) Also see mounting holes

    Now complete the customer is very happy with the first Z8 Bluetooth system with functioning snap in adapter. The Snap in adapter boosts the signal of the RAZR using the Original CPT8000 phone booster and antenna. The RAZR is also charged when plugged into the snap in adapter.

    Z8 Phone Upgrade/Conversion Kit

    This is a life saver.

    Is this an after market kit or a BMW kit?

    Can you give me the source or the part numbers?

    Problem removing curly phone wire

    Help -- I am stuck.

    Bought the bimmernav bluetooth kit for my Z8. Install was going very smoothly, except when it came time to put in the pairing switch.

    The instructions say to trace the curly phone wire back into the tunnel. I cannot find the end of this wire. I have taken apart quite a bit of the parts, but not the entire console.

    What should I do?

    I suppose I could try to take apart the whole console, but I am a little intimidated by this. How do you do it?

    Or is there another trick to reaching the interior end of the curly phone wire?

    Thanks in advance for any help.
