CD ERR is displayed on my stereo

Sound like the radio is asking about unlock code, you will need ask your delaer this information.

The err is short for error.If the cd player accepts a cd and can't read it can cause err to display. The cd also can be scratched or the lens may be dirty or damaged.If you buy a cleaner cd and it doesn't work then its time to replace the radio preferrably an aftermarket because the factory type can cost up to $500 or more.

internal problem in radio,you would have to take it to a dealer to send out for you,

If cleaning didn't help,then replacing is the way to go.You can go to a local stereo shop and see if they can fix it easily.they might know the trick on doing it.It's worth a try.Don't go to Best buy.I know you have seen one as you were driving around town,just pull in and see what's up,They may have fixed one as the same as your Nissan.

dear friend- the error code means the lazer is not reading your cd,if it is a pirate cd it might be the problem,or the lens must be cleaned.

the cd player only is the problem even though it is all in one unit the radio will still play. tr a different disk if no luck then unfortunatley the problem is in the radio itself. you can buy a nice after market radio for alot less money. keep me posted thanks

this generally means the laser is either dirty or the cd player is shot, err 01 is a disc reading problem. Try cleaning lens with cleaning disc first if this does not help i would replace the unit with another. i would recommend replacing it with a cheap aftermarket stereo.

I have seen this a bunch of times always with the same result, take it to a audio repair facility, the sterio has a bad internal circut. No external "quick fix" that i know of

That is short for CD error. this means the CD player has some kind of problem
