Your owners manual should give you some answers. Lacking that, you could get a Chilton/Haynes repair manual for your make/model/year. There are sections for trouble shooting most areas, including the radio (if it's the stock system).

Sounds like the head unit is malfunctioning from how you have described the issue. If so you would need to replace the unit to correct. If it is the same unit that does CD and radio and only part of the features function you will need to replace the faulty unit.

hi there is a option in the settings to automatically search for the station if frequency changes try turning it off to see if that helps
