- Different Types of Bluetooth Car Adapters
- What to Look For When Buying a Bluetooth Car Adapter
- TOP 5 Best Bluetooth Car Adapters
How your wireless Bluetooth adapter works depends on the type of adapter you choose:
- FM Transmitter – uses radio FM frequencies
- AUX-in – plugs directly into your 3.5mm AUX input
- Visor Type – output through its own speakers
Bluetooth adaptors are designed for hands-free calling. Some adapters only allow phone calls while others incorporate streaming music. Some are basic. Some have multi-function button pads. Some have LCD display screens with button pads. Many offer convenient voice-activated controls.
The best Bluetooth car adapter kit for hands-free calling has a high-quality, noise-canceling mic that reduces background road noise. If your vehicle doesn’t have AUX-in, an FM transmitter kit is necessary. However, if open FM frequencies are limited (around cities), there is little other option but to connect via an AUX input.
AUX-in kits are generally the least expensive (averaging about $20). AUX-in kits plug directly into, your stereo 3.5mm AUX input. Bluetooth picks up the audio signal sent from your phone. The wireless signal is decompressed and converted to an analog signal. Your stereo then amplifies the signal it receives.
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 be aware that the cheapest units just aren't worth it! The FM transmission quality must be strong enough to send a clear signal your stereo can pick up. Bluetooth compresses the audio signal, which is converted to an FM radio signal. FM signals have a lot of noise and an unpredictable frequency and low signal-to-noise ratio. The signal noise is apparent even with a good antenna.
Visor-style kits are the most expensive ($50 - $120 range) hands-free Bluetooth car adapter kits because the units have their own built-in speakers as well as a wireless system. There is no feedback, echo, or distortion. Conversations are very clear because the sound is not transmitted through your car speakers. The unit attaches to your sun visor. It is intended for hands-free phone calling but you can also play music through these speakers.
- Audio Performance
The most important audio qualities to look for when buying a Bluetooth adapter kit are signal clarity and signal strength.
Signal Clarity - A satisfying audio experience is a balanced mix void of noise and distortion. There must be a clean signal to ensure that the sound coming out of your speakers is high quality.
Signal Strength – Strong signals determine maximum stereo amplification. Strong signals are loud and generally have a higher signal-to-noise ratio. This also affects clarity.
While some Bluetooth car kits can connect multiple devices, others can only connect with one device at a time. This is not very convenient if you have several passengers that all have a phone, tablet, music, or game devices each wants to use while traveling!
The best Bluetooth adapter for your car is also one that you do not have to configure each time you want to use your device(s). Rather, it automatically pairs with your device(s) when you enter the vehicle. Some remember devices they have been previously paired with and they will automatically connect if they are within range. Pairing is also important if you intend to stream favorite (Pandora) stations. You want your Bluetooth to unobtrusively connect.
- Hands-Free Operation
Hands-free operation is the most important feature of a good Bluetooth adapter. Choose a model that is convenient as well as functional.
- Docking Station
A magnetic docking station can be attached to your car’s surface. Multi-function buttons allow you to control your phone hands-free.
- Stereo Audio Jack Models
These connect to the audio jack with a metal ending. The unit has a multi-function button pad to control the phone hands-free.
- FM Transmitter Plug-In Models
These plug directly into your vehicle’s cigarette lighter.
