Bluetooth is a feature found in both original equipment (OE) and aftermarket car stereos, and it is not limited to any particular car stereo configuration. This wireless communication protocol allows devices to communicate with each other over distances of up to 30 feet, making it ideal for creating small Personal Area Networks (PANs) within a car or truck.

A Bluetooth car stereo is simply a car stereo with built-in Bluetooth capabilities. In most ways, a Bluetooth car stereo is very similar to other car stereos. Also known as a head unit because it controls all the other audio components in the car, a car stereo usually includes a radio, may be able to play CDs or MP3s, has a built-in amplifier or preamplifier output, and is also connected to speakers.

Bluetooth is a communication protocol that allows devices like cell phones and host computers to share data back and forth, but some Bluetooth-enabled devices offer more features than others.

Hands-free calling: this extremely common feature allows you to make calls using a Bluetooth headset, a built-in microphone and a hands-free phone from your car's speakers or cell phone.
Audio Streaming: This feature allows you to stream music, podcasts and other audio from your cell phone to your car stereo system.
Remote App Control: This is a two-way feature that allows you to control your cell phone or specific apps using your car stereo.
Access to Stored Contact Information: This feature allows you to pull information from your cell phone, such as an address book, on your car stereo.

While it is illegal to use a cell phone while driving in many jurisdictions, most laws have exemptions for hands-free calling. While many cell phones offer speaker options and Bluetooth-enabled phones can be paired directly with a headset, a Bluetooth car stereo can provide a more integrated experience.
