What does bluetooth in a car do




















Audio quality varies from case to case with a dynamic bit pool or range of bit rates being negotiated by the transmitting the device your phone and the receiver your car at the time of pairing. Generally speaking, we've found the quality to be good enough for compressed MP3s with only a few isolated examples of a noticeable quality drop.

Users are able to skip tracks forward and backward and pause and resume playback. The most current implementation of AVRCP also includes the communication of metadata artist name, album, song title, and so on and playback state playing, paused, or stopped.

In the future, we may eventually be able to browse media on the connected phone and perform simple searches. Why would you want to connect your car to the Internet? Possible reasons include downloading traffic data, using online search engines to find destinations, and connecting to telematics services.

Different cars work in different ways, using one or more of these three profiles. However, many drivers have a hard time resisting the siren song of their notification beep. MAP allows incoming messages usually SMS to be relayed to your car's infotainment system where they can be displayed or read aloud by a text-to-speech system. No longer will you need to wonder whether that incoming message is an important message from your boss or spouse that requires immediate attention or an unimportant message that can be attended to later.

MAP is a bidirectional communicator, so certain cars can be set to automatically respond with a "Do not disturb" message. In the future, we may even be able to reply to the important messages via voice recognition.

If you've ever paired a phone with a Bluetooth speakerphone or headset, you're familiar with the four-digit PIN input of Bluetooth's legacy pairing system. There is no installation required, either. You simply turn the unit on and set it to your desired frequency.

Since FM frequencies vary from region to region, this will take some tweaking if you typically drive long distances. Another potential challenge is finding an open frequency. In a major city like San Francisco, it is often easier said than done.

In remote areas, static can wreak havoc on your audio experience, too. The options are limitless. Bluetooth resembles an FM transmitter and works in similar ways.

Neither of them requires radio waves in order to connect to other devices. Bluetooth gives you a clear, crisp, static-free sound, which always beats a shakey FM frequency. The first hands-free car kit arrived all the way back in , but it took a while for other manufacturers to join the party. Today, most new mainstream cars come with Bluetooth or at least the option to add it for a fee. That means everything from superminis such as the Ford Fiesta to executive saloons such as the BMW 3 Series will have the tech.

Not all systems are born equal. While more advanced options bring in the ability to have phone calls through your car. Press the phone symbol button on your steering wheel or dashboard and you're likely to be presented with a list of contacts on the dashboard display. You can normally program in your favourites so that they appear first. To make a call, you typically scroll to the name that you're looking for and then select it.

You've also got the option of manually entering a phone number. An in-car microphone picks up everything that you say, while you hear the person on the other end of the line through the car's speakers. The stereo pauses any music or radio broadcast when you make a call, or if you receive one. Most models allow you to answer and end a call with a clear button on the steering wheel, which could have a phone symbol on it, or it could be the multipurpose 'ok' button.
