"  The Parrot 3200 LS-COLOR integrates your cellphone with your car stereo. Q: Can I wire Bluetooth into my existing car stereo? A: Definitely -- but make sure it&amp;#039;s worth your time and money. Several companies, such as Motorola and Parrot, make aftermarket Bluetooth car kits that wire into your stereo. The Parrot 3200 LS-COLOR, for instance, not only adds Bluetooth calling from your cellphone over the car&amp;#039;s audio system, but also will mute your music when you have an incoming call, just like the integrated from-the-factory Bluetooth systems. Of course, you&amp;#039;ll pay a few hundred bucks for an integrated system, plus installation charges should you opt to have a tech open up your dash to get at your stereo wires. The same companies also make Bluetooth speakerphone devices that don&amp;#039;t require any special wiring and are powered through the cigarette lighter or rechargeable batteries. However, these devices do not use your car&amp;#039;s speakers nor do they automatically mute the music when a call comes in. So, ask yourself if you want a device with a slightly nicer set of features that is permanently wired to your car, or if you&amp;#039;d be willing to trade the built-in features of an installed unit for the flexibility of one that&amp;#039;s portable. If you decide to go with an integrated kit, you should also consider if it is worth it to you to spring for a new stereo head unit that has Bluetooth built in -- prices start at around $400.
