Bluetooth in your car allows wireless, hands-free access to your phone, radio and personal music players. If your car does not have Bluetooth in it already, having it installed will make it so much more convenient and safer when making calls and changing songs. Wiring the Bluetooth into your car's audio system can be challenging if you do not have experience in automotive electrics, so you may need professional help to install.
Find a Bluetooth kit for your car online or at an automotive accessory store. Generally the more expensive it is, the better the quality it will be. If you buy at a store, they may be able to install the Bluetooth kit for you, usually at an extra cost. This is recommended if you are not comfortable cutting wires in your car.
Connect the Bluetooth device to your car's audio system. If your car stereo has ISO plugs, simply disconnect the car stereo's audio and power leads. Join the female connectors of the mute cable and power supply cable to the car stereo. Join the vehicle's audio and power cables to the male connectors. If you do not have an ISO plug, purchase an adaptor, or manually splice the wires. This involves cutting the audio and power cables and physically connecting the wires to the Bluetooth control console. Consult the instructions and your car's manual to find out which wires you should splice together, as this will vary among different kits and cars.
Position the microphone which comes with the kit above the driver's seat. Fix it in place either by screwing it in or using double-sided sticky tape. It should be no more than 16 inches away from where your mouth will be to ensure clarity when speaking. Make sure you do not place it behind any obstructions such as the sun shade or rear-view mirror.
Install the control console which comes with your Bluetooth somewhere suitable on your dashboard. It should not get in the way of any of the car's controls or obstruct your view; but be in a position where you can reach and control it comfortably. You may have a separate display with your Bluetooth kit; be sure to place this somewhere you can see easily, but where it does not obstruct your view or your car's controls.
Pair up your cellular phone or other device to the Bluetooth to try it out. You will probably be asked for a code to pair the device to the Bluetooth. This should be in your instructions, but the default code is usually 0000. If there are any problems, consult the retailer.
