The Metra(R) MET-TY3 data interface is a cost-effective solution that allows installers to retain certain vehicle functions that are normally lost when replacing the factory radio on select 2001-2015 Toyota(R) and Lexus(R) vehicles. It is engineered for broad compatibility across a wide variety of radio brands and models, making it ideal for integrating radios purchased from online retailers. This interface delivers NAV outputs, accessory power, and quick DIP switch setup for seamless steering wheel control configuration - making installation faster and easier.
