2001m-Radio and cd issues

Here's my question, the radio and 4 cd changer is driving me nuts. The 1sel keeps popping up on radio a lot and every time it does what ever is playing either stops for a few seconds or I have to reset it by hitting the on/off button. Then sometimes it will just freeze up then I have to pull fuse “19” to reset the audio system. Any ideas out there on how to fix this.

Thanks in advance
