Pioneer’s Sound Tune app is a great way to bring the sound of high-end audio to a basic factory car stereo and speaker set.
All operations are performed easily through a smartphone and a wide range of settings are accessible.

For USB connections
- This function is compatible with a phone that runs Android 5.0 up to 7.1.2 and also supports AOA (Android Open Accessory) 2.0 but the compatibility depends on the smartphone.
- Some Android devices connected via AOA 2.0 may not work properly or emit sounds due to their own software design regardless of the OS version.
