While Bluetooth connectivity is widely available in new cars, it’s easy to add at least some level of the same functionality to any car with any head unit. Depending on the route you go, you may be able to gain access to useful features such as hands-free calling or music streaming. You may even be able to control your car radio using your smartphone.
Three Ways to Get Bluetooth for a Car
If your current vehicle doesn’t have Bluetooth connectivity, but your smartphone or tablet does, you can add the technology to any car using one of three methods. Install a Universal Bluetooth car kit. The advantages of this method include:
It is the least expensive option.Universal kits are platform agnostic.Different kits offer different functionality.
Install a vehicle-specific Bluetooth adapter. Advantages and limitations are:
This method is only available if your head unit is “Bluetooth-ready.“You can keep your factory radio.The adapter offers better integration and more features than a universal kit.
Upgrade to a Bluetooth car stereo. Advantages and disadvantages include:
This approach is the only way to get full Bluetooth functionality in any car. Replacing your stereo is more expensive than buying a Bluetooth car kit. Upgrading requires you to replace your existing radio completely.
The best way to get Bluetooth in your car depends on your budget and the kind of stereo you have in your car. If you have a Bluetooth-ready aftermarket car stereo, the best and cheapest way is to buy the appropriate stereo-specific adapter. In other cases, a Bluetooth car kit is the most straightforward way to get Bluetooth in your car. The most expensive option is to replace your car stereo.
Add a Bluetooth Radio Adapter
Some head units are Bluetooth-ready in that while they don’t have built-in Bluetooth functionality, you can add it later with a separate peripheral device. These devices typically consist of a small box that contains a Bluetooth radio and other electronics and a wire or wires that you plug into the car’s head unit. Installation tends to be a relatively simple operation, although you usually have to remove the head unit to access the adapter port. Since these Bluetooth radio adapters aren’t universal, you must buy a device designed specifically for your car stereo. If your car’s head unit wasn’t designed with a Bluetooth adapter in mind, you have to add Bluetooth to your car in some other way.
Install a Bluetooth Car Kit
If there isn’t a Bluetooth adapter designed for your head unit, then a universal Bluetooth car kit is another easy, low-cost way to add Bluetooth connectivity to a car. Plenty of options are out there, so it’s important to understand the different choices available to you. The main types of Bluetooth car kits include:
SpeakerphonesHands-free calling kitsMusic-streaming kitsCombination units
Bluetooth speakerphones tend to be relatively simple devices that don’t interface with the car radio. You pair your cellphone to the speakerphone and then use it like a headset that you don’t wear in your ear. That makes the installation quick, but you miss out on a lot of neat Bluetooth features. The two main features to look for in a Bluetooth car kit are hands-free calling and music streaming. A good Bluetooth car kit can turn down or mute your radio during calls, which is a useful safety feature. The ability to wirelessly stream music from your phone, including internet streaming radio services such as Pandora and Last.FM is also a welcome touch.
Upgrade to a Bluetooth Car Stereo
While upgrading to a Bluetooth car stereo isn’t a cheap option, it is the only way to add complete Bluetooth functionality and connectivity to any vehicle. If you’re on the verge of a sound system overhaul anyway and you’re interested in Bluetooth, look for head units that include that functionality out of the box. Full Bluetooth integration means that your head unit can display caller information and song data when you’re streaming music and may be able to dial your phone or control apps via a touchscreen interface. Aside from the price, the only other downside of upgrading to a Bluetooth car stereo is that it requires removing the existing radio. If you want to keep your factory look or any particular functionality unique to your car, it’s worth checking into whether a Bluetooth adapter is available.
