Frequently Asked Questions
How to install an FM transmitter
FM transmitters are easy to install and most have a very similar installation process. Start by plugging the device into your aux socket or cigarette lighter. Then go to your smartphone and find it in Bluetooth settings. Then tune your vehicles radio to a blank radio station then pair the transmitter to that same station.
Are there any disadvantages of FM transmitters?
FM transmitters have a lot of positive benefits but there are a few flaws to take note of. The audio signal can potentially be too loud which can lead to distorted audio. Another thing to note is that you need to turn off the transmitter when it’s not in use and not all transmitters turn off automatically with your vehicle.
FM Transmitter vs Bluetooth Adapter
Bluetooth adapters use digital transmissions in order to carry more information and provide better sound than an FM transmission. FM transmitters transfer Bluetooth from your phone that is picked up by your FM radio.
