Currently my phone is simply connected to my radio’s AUX input with a cable, and if I want to change songs I must do so from the phone. Modern raidos have integrated Bluetooth capabilities, allowing you to pair your radio to your phone wirelessly. In some cases, pausing and skipping tracks can be done directly from the radio’s buttons – safer than waking up and unlocking your phone to change songs within the music player app.
I could have purchased such a radio, but I already had a perfectly fine JVC unit I installed not even two years ago. It has two AUX inputs, the one in the front I’ve been using, and a special Bluetooth AUX input in the rear. Although designed for use with a JVC accessory, I decided to build my own Bluetooth receiver for my car.
