The APUNISW5 is a universal steering wheel control interface to suit over 900 vehicle applications, including Australian built models. It retains a host of vital OEM vehicle features when upgrading the head unit to an aftermarket model, including steering wheel controls, phone buttons, settings menus and more. The vehicle button configuration can also be completely remapped, allowing drivers to tailor desired functions on a long or short press in all vehicles on any platform via a simple PC program which is free to download. For vehicles with older analogue systems, the interface features a programming function to ensure compatibility across the board.
