Thanks to the long-range transmitter, you can listen to music played from your smartphone via the car radio. It can come from your phone's memory as well as from services such as Tidal or Spotify. All you have to do is pair your phone with the accessory and search for the right frequency on the radio. You can also play the music from your flash drive or microSD memory card, which has a dedicated slot. In the same role you can use the accessory as a navigation sound amplifier - it is played through the radio. Compatible audio file formats are MP3, VMA, WAV and FLAC.
