My guess would be that someone crossed some wires somewhere for it to behave like that or the only other reason would be that your CDR-220 unit is starting to go bad. Did you recently add anything new to your car that might have caused this like added a new antenna or ipod connector? I dont think its polarity as that would have caused the radio fuse to pop.
I don't think its programming. If nothing was changed and this problem only started now, you can try disconnecting the car battery, wait an hr, connect battery back on and enter the radio code to see if its any better as these electronics sometimes need a reboot too !
best
