Why would your CD player register e20 then spit the CD out?
Do you have the owner's manual for your vehicle (if it is a
factory CD player) or the manual for the CD player itself? If so it
should contain a chart listing the various error codes and what
they indicate. Without a manual to assist, I would assume that
either the CD is scratched or in some other way unreadable
(sometimes CDs made by a computer's CD burner cannot be read), or
the reading laser in the CD player is covered by dust particles and
must be cleaned. If you take the vehicle to a car audio shop they
should be able to clean it for you. If that doesn't help, they will
be able to further diagnose the problem. It happened to my CD
player with ALL my CD's. I tried a procedure and it began working
again for about 3 months. I wrapped a baby wipe with alcohol around
a CD. Then I inserted it gently into the slot, and as the player
pulled it, I gently moved it in and out, careful to hang on to the
baby wipe so it would not get caught or jammed in the slot. After
moving it in and out for about five times, I pulled it out. I then
inserted a store-bought CD cleaner disk and pushed the button to
track 2 as the instructions said. I let the CD cleaner do it's
thing, and when it was done, I waited a bout 30 seconds and
inserted a regular CD, and it worked fine. Good luck!
