Access functions including presets, fast forward and rewind, and artist and album search. Users can also adjust audio and Bluetooth settings. Connect to Spotify and find the songs you love instantly, or let Spotify play you something new. With support for Spotify, just connect your compatible smartphone to a Pioneer Car Receiver to fill your ride with everything from classic tracks to the latest hits. This allows you to experience more natural sound quality during calls. With dual phone connection, you can receive call from two different devices, eliminating the need to switch between or pair and unpair devices.
