How does a Bluetooth car adapter work?

How your Bluetooth wireless adapter works depends on the type of adapter you choose:

FM transmitter – uses FM radio frequencies

AUX-in – connects directly to the 3.5 mm AUX input.

Sight type – output via own speakers

Bluetooth adapters are designed for hands-free operation. Some adapters only allow phone calls, while others work with music streaming. Some are very straightforward. Some have multifunctional keypads. Some have LCD screens with keypads. Many offer convenient, voice-activated controls.

The best Bluetooth car adapter set for hands-free calling has a high-quality noise-canceling microphone that reduces background noise. If your car does not have an AUX input, an FM transmitter kit is required. However, if the open FM frequencies are limited (in cities), there is no other option than to connect via an AUX input.

Different types of Bluetooth Car Adapters

AUX input

AUX-In-Kits are usually the cheapest (on average about 20 US-Dollar). AUX-In kits are connected directly to the 3.5 mm AUX input of your stereo system. Bluetooth receives the audio signal sent by your cell phone. The wireless signal is decompressed and converted into an analog signal. Your stereo system then amplifies the received signal.

FM Transmitter

FM transmitters are really only recommended for those who do not have AUX inputs in their vehicles. You get what you pay for with these FM transmitters, so keep in mind that the cheapest devices just aren’t worth it! The FM transmission quality must be strong enough to send a clear signal that your stereo system can pick up.

Bluetooth compresses the audio signal, which is converted into an FM radio signal. FM signals have a lot of noise and an unpredictable frequency and a low signal-to-noise ratio. The signal noise can be seen even with a good antenna.

Visor Style

Visor style kits are the most expensive ($50 – $120 range) Bluetooth handsfree car adapter kits, as the units have their own built-in speakers as well as a wireless system. There is no feedback, echo, or distortion. The conversations are very clear because the sound is not transmitted through your car speakers. The unit is attached to your sun visor. It is designed for hands-free calling, but you can also play music through these speakers.
