The TOY-SC1 is designed to be compatible with select Toyota, Lexus, and Scion vehicles that support Satellite Radio operation. The interface is designed to replace the factory satellite tuner in your Toyota, Lexus or Scion vehicle. It is also compatible with systems that do not have the factory satellite tuner installed. With this kit you will be able to control SIRIUS Radio programming such as changing channels, category search, set presets, and category tune. Please note - you will need to purchase either the SCC1 SIRIUSConnect tuner or SIRIUSConnect Vehicle Kit (to use a SIIRUS compatible plug and play receiver) in order to receive SIRIUS Radio service.
