A.  Cargo area install of Bluetooth module

The first part of the installation involves installing the Bluetooth electronics into the rear of the car.


A.1 Open the truck and remove any plastic floor liner or trunk mat (if present). Remove left rear access panel to reveal wiring harness and (if so equipped) the navigation system & CD/DVD drive


A.2 We are looking for the phone connector. This is a 25-way D type connector that looks just like a 25-way PC serial plug/printer plug. It is black and shown clealy in photo A.2. If it is not immediately obvious, take that flashlight and have a good look around. It may be cable tied up into the harness
and obscured by the carpeting or taped on the side of the cargo area.


If you have found the connector, proceed to step A.6



A.3 If you haven't yet found the black connector, we need to look a little deeper. Lift the cargo floor and secure the clasp to the roof so as to hold the floor (as shown by BMW for gaining access to the spare tire).


We will now remove a black plastic piece of trim to the left of the spare wheel.


Remove three 10mm bolts that are holding down the black plastic trim to the left of the wheel. Remove this black plastic trim.



A.4 You will now have exposed more of the wiring harness. Locate the phone connector. This may be tied into the cable harness; if so, release by carefully cutting the cable ties.


A.5 Replace the black plastic trim piece and the three nuts ensuring that the 25-way phone connector is now accessible as in photo A.5. Replace cargo floor and secure in place.



A.6 Connect the caughtbluehanded.com interface to the Bluetooth module.



A.7 Install the caughtbluehanded.com interface module by plugging the car 25 way socket into the adaptor box. Secure the adaptor and the Bluetooth module with cable ties.


A.8 Close up the rear storage area and replace floor mats You are now finished with the trunk install

B.  Microphone

We now need to install the microphone. This Bluetooth kit uses its own microphone but makes use of the BMW wiring.


B.1 Remove the front lighting unit from the roof; take care to locate the metal retaining tabs and release by levering out as show in figure B1.1. Take special care not to damage the surrounding plastic. The photo shows use of a screwdriver to achieve this ­ you may find a credit card works just as well and with less chance of damaging the plastic.


B.2 Reach into the opening and press out the factory microphone cover and disconnect the microphone
wiring.



B.3 Take the new microphone and gently feed the 3-pin connector through the headliner by the rear view mirror. A pair of very small pliers or tweezers is helpful. Follow the existing wiring and feed the 3-pin connector through to the factory microphone housing. Connect the 3-pin connector to the car connector.

At this stage consider where you may want to position the microphone. (See photos in B.6.) It is neat to feed the wire through the headliner such that the sun visor light clip is used to pass the microphone wire behind the rear view mirror.



B.4 Replace the factory microphone/cover by pushing firmly back into place


B.5 Replace the front interior light unit



B.6 Route the microphone cable into the headliner and place the microphone somewhere convenient, for example in the drivers sun shade. Two sample locations are shown. In the second photo I routed the microphone cable through the headliner to the lamp behind the sun visor. The exact positioning of the microphone is a matter of personal preference.

C.  Bluetooth pairing and call

Using your phone instructions, enable Bluetooth on your cell phone. Initiate pairing and if needed the access code is `1234'. Your phone should pair with the `Parrot' Bluetooth module.

From your phone handset, while in Bluetooth headset mode, place a call and enjoy the hands-free Bluetooth.
