2013 Chrysler 200 radio stations don't work.

What is your question?

Approximately 2 months the radio stations in my car started to go in and out, but only the radio stations the CD and the AUX work with no problems. Then about 2 weeks ago the radio stations stop working, the AUX and the CD continued to work without any problems. I removed the radio and all cables are connected as well as all fuses are in working order. Someone told me the amp is the issue but I have a simple radio so I don't believe my car has an external amplifier.

What makes this problem better or worse?

Nothing makes a difference.

How long has your 2013 Chrysler 200 had this problem?

2 months ago radio will go quiet and 2 weeks ago it stopped working.
