If you've recently purchased a new car—or even if you have a luxury car that's many years old—chances are you have Bluetooth hands-free calling connectivity. And even if you have an older vehicle, it's a tech-forward safety device that you definitely should be considering if you ever use the phone while driving. What Bluetooth allows, after you properly connect your phone with your system, is completely wireless access to calling functions from your phone through your vehicle—via the dash, a control screen, steering-wheel buttons, or voice commands. In theory, it's easier as you'll keep both hands on the wheel and won't need to look down to dial numbers, hold a handset to your ear, or do things like change the volume. What is Bluetooth?

Use hands-free calling for safer journeys
In Stock. I have a newer vehicle with Bluetooth support for audio streaming and handsfree phone operation, and I absolutely love it.

I've had no trouble connecting several iPhones to it for audio streaming, and I've used the handsfree audio only once, but it works well.
Numerous aftermarket companies allow motorists to benefit from useful connectivity and safety features without having to buy a new car. Bluetooth is a great example of this — it has been around for years, and it used to be an expensive option offered solely on high-end cars, but it has become a cheap, easy upgrade on any vehicle regardless of its age or value. As the name implies, these standalone units work in just about any car thanks to a built-in speaker and microphone. There are pros and cons to these systems. Note that mounting the device with tape could leave a nasty mark on your dashboard. There are a few universal devices that will wire into your head unit and can add music streaming to the list of functionalities, but that makes the installation process a bit more complicated. With patience, common tools, and a couple of hours, most people can replace their stereo system. Fortunately, even the most affordable units feature Bluetooth integration for hands-free calling.
