CD Errors
· E20 or CHECK CD : Cause(s): The CD player cannot focus on the disc or there is an internal focus problem. Correction(s): Try cleaning the disc or using a new disc. Make sure the disc is loaded correctly. The road could be too rough or there is too much humidity.

If your player is an AC Delco giving you the e20 error and only on your burnt discs the lens is probably not shot. It's just very dirty and can only read professional grade CDs. The remedy is to open the CD player and clean the disc with 70% Isopropyl Alcohol.

You will need a small adjustable wrench or ratchet set as well as a T-7 torx bit. You only need to remove the bottom of the player and the front piece in order to get to the CD player inside. Unscrewing other screws will just lead to having to more to reassemble. Once you get to the heart of the CD player you will need to release it by unscrewing the torx screws and then turning the player over and you will see the lens. Put some alcohol on a q tip and gently rub the lens a few times. then reverse all disassembly and put the player back together.

When you reinstall the CD player it should play all of your CDs

ALSO be sure to disconnect the negative in the battery before removing any electric devices to prevent short circuiting. And only reconnect it after you have reinstalled the CD player.
