2010 fusion radio

My 2010 fusion radio sound quality isn’t as good as when car was new. Also seems to vary on certain days. Has any one had problems with their Sony factory system & what was the fix?

Is it the am/fm sound quality causing the problem? If so, that might be a problem w/the antenna. Try wiggling it while the radio is on, see if you notice any difference. And see if you can see where the antenna base is grounded to the chassis, notice any loose connections or corrosion there?
