I have a 98, I feel like I'm blasting to the past because it has a cassette player. I don't wanna change the radio for aftermarket in order to keep the original integrity of the car. I was thinking about the 6 CD changer that goes in the trunk; direct screw on? Or does that need extra wiring?

 

the wiring should be there, you can also do a RNS-E conversion. Nav and what nots

 

Radio signals are electromagnetic waves of frequencies. Satellite radio is radio different terrestrial technology. An analogue transmission encoders based antenna. Satellite radio satellite network for data transmission in stereo.
