What wrong when you put a cd in radio and it come back out and radio screen say e20 or e23

your cd player is unable to read the discs. may want to try some of the computer cleaner spray/ duster. spray the computer duster into the cd slot and it may clean the laser to let it work again.

It means the cd laser lens is dirty. clean it and it should go away. You will probably have to remove the radio or get a disc cleaner.

You need to replace the cd lens.

Cleaning with what-a cleaning CD? If so, she's most likely toast now, sorry :o(
E20 is a read error...could be bad media (ie CD format like from your PC). Otherwise, unplug the changer and plug back in.
Good Luck

If the CD is over 60 minutes it will not play on domestic cars

Hi try a known good CD if E20 still comes up then there is an internial lazer problem not being able to read the disc

Hi E20 mean's
The CD player cannot focus on the disc or there is an internal focus problem.
try a known good CD and if it still displays E20 then you will have take it to a radio repair shop

I checked my manual and could not find any results for an error e23, there is an error e20 for the reasons The disk is upside down
It is dirty scratched or wet
There's too much moisture in the air,wait about an hour and try again.
From presonel experiance these decks will not play MP3's only disks that have been burned using
the WAV. format.

It's just an error message. It stands for Error 20. There is no way to fix the problem. It only reads cd's that it wants. But if it does play a cd, then suddenly stops, and says E20 and spits the cd out, it's most likely because the cd player got too hot. My car does that all the time. And it won't play a lot of burned cd's. Hope this helped.

Just found this... doesn't help me since I'm using the tape deck and not the CD part... E22 : Motor Error Cause(s): The CD motor is not handling the compact disc properly. Correction(s): Service or exchange the unit at an ACDelcoã‚â® Service Center.
