The IS300, Lexus' sport sedan, comes equipped with a standard stereo deck that includes an in-dash CD player, or optional deck that is capable of receiving satellite radio. Lexus owners can upgrade their factory head unit or replace their stock deck with an aftermarket model. You can pay for a professional installation by a car audio technician, or you can install the new audio unit yourself to save time and money.
