I just bought a Neon sport 97 with a 5 cd player install in the trunk. There is a remote beside the radio but when i press play there is nothing. I think there is something i don't know. At the dealer they told me there is a radio position and think it's 98.3 FM Someone know how it works ??

 

THat type has an FM modulator so it is like picking up a radio station. The FM modulator is coinnected through the antenna so make sure that connection is good. Also you will need to get the make and model and go to there website and see what the FM station is.
