Bluetooth Car Stereo Basics

Hands-free calling, music streaming, and more

Bluetooth is a feature found in both original equipment (OE) and aftermarket car stereos and is not limited to specific car stereo configurations. This wireless communication protocol allows devices to communicate with each other up to 30 feet away, making it ideal for creating small personal area networks (PANs) in cars or trucks.

The safety, convenience and entertainment features provided by Bluetooth car stereos vary widely, but are not limited to the head units with which they are built. Even if the head unit doesn’t have Bluetooth, you can still take advantage of features such as hands-free calling and internet audio streaming with a suitable add-on kit.

What is a Bluetooth car radio?

Bluetooth car radio is a car radio with built-in bluetooth function. In many ways, a Bluetooth car radio is like any other car radio. A car stereo, also known as a head unit, because it controls all other audio components in the car, usually includes a radio, can play CDs or MP3s, and has an amplifier or preamplifier output built in. It also connects to speakers.

The Bluetooth car stereo also offers Bluetooth connectivity. This usually allows you to connect them to your phone, wireless earphones or headsets, and other wearable electronics. The best car stereos on the market include Bluetooth.

What is Bluetooth and how is it used in cars?

Bluetooth is a communication protocol that allows devices such as cell phones and head units to exchange data, but some Bluetooth enabled devices offer more features than others.

Certain features offered by a particular Bluetooth car stereo depend on the profile for which it was designed, so some head units offer much more than others.

The most common features of a Bluetooth car radio are:

  • Hands-free calling: This popular feature allows you to make calls through Bluetooth earphones, a built-in microphone and car speaker, or your phone’s speakerphone.
  • Audio Streaming: This feature allows you to stream music, podcasts and other audio from your phone to your car audio system.
  • Remote App Control: An interactive feature that allows you to control your phone or specific apps with your car stereo.
  • Access stored contact information: This feature allows you to access information on your phone, such as: B. Address book on car radio.

Each feature uses one or more profiles in the “Bluetooth Stack”, so all devices paired with the head unit must be on the same side for everything to work properly.

Bluetooth car radio and hands-free calling

Using a cell phone while driving is illegal in many jurisdictions, but most laws provide exceptions for hands-free calling. While many phones offer a hands-free option and allow you to pair your Bluetooth enabled phone directly with your headset, a Bluetooth car stereo can provide a much more integrated experience.

There are two profiles you can use to facilitate hands-free calling on your Bluetooth car stereo.

  • Headset Profile (HSP): Commonly used in hands-free kits. It provides only basic functions.
  • Hands Free Profile (HFP): Full Feature. Usually found on bluetooth car radios.

HSPs are more commonly found in aftermarket hands-free kits, while HFPs offer more features. Typically, when you pair your phone with a child who has a Bluetooth car stereo or a hands-free kit using HSP, they work like Bluetooth earphones and provide only very basic connectivity.

Normally, when you pair your phone with a device that supports the hands-free profile, the head unit will turn down or mute the volume when a call is initiated. This type of Bluetooth integration provides significant convenience and security as you do not have to take your hands off the steering wheel to operate the stereo system.

Access to saved contacts

Generally, if your Bluetooth car stereo supports Object Push Profile (OPP) or Phone Book Access Profile (PBAP), you can use the primary device to access contact information stored on your phone.

OPP can transmit contact information to the primary device and store it in the Bluetooth stereo device’s memory. This will give you access to information about hands-free calls, but you will need to manually resend them after updating your contacts.

The Phonebook Access Profile is a bit more advanced because it allows the console to retrieve contact information from a paired phone at any time. This makes it easier to update your contact information, but it can also improve your hands-free experience.

audio streaming

Head units that support Bluetooth audio streaming allow you to wirelessly stream music and other sound files from your phone to your car stereo. If you have music, audiobooks, or other content on your phone, you can play it on a Bluetooth car stereo that supports Advanced Audio Distribution Profile (A2DP).

It can also play Internet radios such as Pandora, Last.fm, and Spotify. You can also control audio streaming from the head unit if your Bluetooth car stereo supports the Audio/Video Remote Control Profile (AVRCP).

Remote Bluetooth App Control

In addition to controlling streaming media via AVRCP, other Bluetooth profiles allow remote control via a variety of other apps from a paired phone. The Serial Port Profile (SPP) allows the Bluetooth car stereo to actually run apps like Pandora on the phone, which can then receive and control streaming media using A2DP and AVRCP.

bluetooth car radio alternative

If your car stereo doesn’t have a Bluetooth connection, but your phone has a Bluetooth connection, you can still use many of these features. The experience isn’t quite as smooth as a Bluetooth car stereo can offer, but there are a number of kits and other hardware that offer hands-free calling, audio streaming, and other features. Potential Bluetooth car stereo alternatives include:

  • bluetooth hands free kit
  • mounted speakerphone
  • bluetooth audio streaming kit

Hands-Free Calling, Music Streaming, and More

Bluetooth is a feature that can be found in both original equipment (OE) and aftermarket car stereos, and it’s not limited to any particular car stereo configuration. This wireless communication protocol allows devices to communicate with each other across distances of up to 30 feet, so it is ideal for creating a small, personal area network (PAN) inside a car or truck.

The safety, convenience, and entertainment features offered by Bluetooth car stereos are fairly diverse, but they’re not limited to head units that have the functionality built in. Even if your head unit doesn’t have Bluetooth, you may still be able to take advantage of features like hands-free calling and even internet audio streaming with the right add-on kit.

What is a Bluetooth Car Stereo?

A Bluetooth car stereo is just a car stereo that has built-in Bluetooth capabilities. In most respects, a Bluetooth car stereo is a lot like any other car stereo. Also known as a head unit, since it controls every other audio component in your car, a car stereo will usually include a radio, may be able to play CDs or MP3s, will have either a built-in amplifier or pre-amp outputs, and also connects to the speakers.

In addition to all of that, a Bluetooth car stereo also includes Bluetooth connectivity. This typically allows it to connect to your phone, a wireless earpiece or headphones, and other portable electronics. Many of the best car radios on the market include Bluetooth.

What is Bluetooth and How is it Used in Cars?

Bluetooth is a communication protocol that allows devices like cellular phones and head units to share data back and forth, but some Bluetooth-enabled devices offer more functionality than others.

The specific features that any given Bluetooth car stereo offers are dependent on the profiles that it is designed to make use of, so some head units offer significantly more functionality than others.

Some of the most common features offered by Bluetooth car stereos include:

Hands-free calling: This extremely common feature allows you to place calls using a Bluetooth earpiece, a built-in microphone and your car speakers, or your phone’s speakerphone.
Audio streaming: This feature allows you to stream music, podcasts, and other audio from your phone to your car audio system.
Remote app control: This is a two-way feature that allows you to control your phone, or specific apps, with your car stereo.
Access to stored contact information: This feature allows you to pull up information from your phone, like your address book, on your car stereo.

Each feature makes use of one or more profiles in the “Bluetooth stack,” so the head unit and any paired devices all need to be on the same page for everything to work properly.

Bluetooth Car Stereos and Hands-Free Calling

While it’s illegal to use a cellular phone when driving in many jurisdictions, most of those laws have exemptions for hands-free calling. And though many cellular phones offer speakerphone options, and a Bluetooth-enabled cell phone can be paired directly to a headset, a Bluetooth car stereo can offer a much more integrated experience.

There are two profiles that Bluetooth car stereos can use to facilitate hands free calling:

Headset profile (HSP): Usually found in hands-free calling kits. Offers basic functionality only.
Hands-free profile (HFP): More fully-featured. Usually found in Bluetooth car stereos.

HSP is more commonly found in aftermarket hands-free calling kits, while HFP offers deeper functionality. When you pair your cellular phone to a Bluetooth car stereo or hands-free calling kid that uses HSP, it will usually just work like a Bluetooth earpiece and provide very basic connectivity.

When you pair your phone to a device that supports the hands-free profile, the head unit will typically lower or mute the volume when a call is initiated. Since that saves you from having to remove your hands from the wheel to operate the stereo, this type of Bluetooth integration offers a significant level of convenience and increased safety.

Access to Stored Contacts

When a Bluetooth car stereo supports either the object push profile (OPP) or Phonebook Access Profile (PBAP), it will typically allow you to use the head unit to access the contact information that’s stored on your phone.

OPP sends contact information to the head unit, where it can be stored in the memory of the Bluetooth stereo. That allows you to access the information for hands-free calling, but you have to manually resend contacts after updating them.

Phonebook access profile is a little more advanced, in that the head unit is able to pull contact information from a paired cellular phone at any time. That makes it easier to update contact info, but it can also result in an improved hands-free calling experience.

Audio Streaming

Head units that support Bluetooth audio streaming allow you to wirelessly send music and other sound files from your phone to your car stereo. If you have music, audio books, or other content on your phone, a Bluetooth car stereo that supports the advanced audio distribution profile (A2DP) will be able to play it.

Additionally, you may be able to play Internet radio like Pandora, Last.fm and Spotify. And if your Bluetooth car stereo supports the audio/video remote control profile (AVRCP), you can even control the streaming audio from the head unit.

Remote Bluetooth App Control

In addition to controlling streaming media via AVRCP, other Bluetooth profiles can provide remote control over various other apps on a paired phone. Using the serial port profile (SPP), a Bluetooth car stereo can actually remotely launch apps like Pandora on your phone, after which A2DP and AVRCP can be used to receive and control the streaming media.
