Thank you for viewing. [Product Name] Galleyra Steering Remote Control Adapter Infrared Type for Toyota/Daihatsu GAL-TAF03. [Product Description] ◆Enables the use of steering wheel switches!! This unit allows you to use steering wheel switches that become unusable when installing aftermarket audio or navigation systems. For Toyota/Daihatsu vehicles, 8 buttons in total can be used: 5 audio-related buttons on the left (volume up, volume down, skip forward, skip backward, mode) and 3 navigation-related buttons on the right (on-hook, off-hook, voice). * Steering wheel switches are called by different names depending on the vehicle manufacturer, such as steering remote control, steer switch, handle switch, or handle remote control, but they all refer to the audio operation switches located on the steering wheel (handle). Regarding installation, please read the instructions and either request a professional or do it at your own risk. Thank you for your consideration.
