The HF850 Bluetooth Car Kit by Motorola mounts to your car to provide a permanent hands-free solution. The car kit includes a microphone and speaker and is compatible with most Bluetooth enabled phones. It connects automatically to your phone, once you've completed the steps for pairing. Because the HF850 needs to be connected to your vehicle's fuse box and stereo system, it is wise to consult a professional to assist you with this process unless you have professional-level experience yourself.
Mount the junction box, barcode side out, under your dash. Use the screws provided in the kit.
Remove all fuses from the fuse kit and tape them to their correct holders. Wait to reinsert fuses until you complete and inspect all connections in the steps that follow
Connect the green ignition sense wire (3 amp fuse) to an ignition-switched location on the fuse block.
Connect the orange entertainment mute wire to your car's entertainment (car radio) system. Be aware that not all vehicles will support this function.
Connect your fuse kit's red primary lead to a 4 to 5 amp fuse point in your vehicle's fuse box.
Connect your fuse kit's black wire to the vehicle chassis. Inspect your connections and reinsert the fuses.
Plug the microphone in to the Bluetooth Junction box.
Find a location no more than 16 inches from the driver, where the microphone can point towards the driver with no obstructions.
Clip the microphone firmly into place, where it will not vibrate. Do not clip the microphone on the visor.
Mount the speaker either on your transmission hump or below your dash.
Point the speaker in a direction that does not directly face the microphone.
Connect the speaker to the Bluetooth Junction box.
