Converters in this department plug into EXISTING factory RSE (Rear Seat Entertainment) or factory DVD ports on the factory radio. If your radio is equipped with the option to interface with a FACTORY DVD system (which you DO NOT HAVE) you can use that port to feed audio in. Some advantages of going through the RSE port is that the factory system will see it as a DVD and usually all other options such as external changers and factory satellite can still remain active.
