My cd player will not read any type cd, i get this eror code"Check cd". Can anyone help?

These CD players are on crack...Sometimes right after I start my car, I get the error code and it'll spit out what ever CD sat in the player over night. I'm not saying you need to, but if you end up replacing the player, check on Ebay, because radios are pretty cheap...Much cheaper than the dealer.
