Err on CD player....2005 Honda CRV

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

Either it's a bad CD (format, or scratches), or you have a faulty CD Player. If the CD player is bad, it is likely much cheaper to just buy a new one, than to fix the factory one.

Disconnect the battery for thirty minutes, and then reconnect it, then try to enter the code that was given to you.

Remove the fuse to your radio or disconnect the battery for 1 min, once reconnected. This should reset the radio again, if it does not reset the radio. Your going to have get your radio re-booted at the dealer if it's a soft wear issue and if it's a mechanical issue. The Tech2 scanner will indicate that when trying to re boot the radio.
Thank you for using fixya.

that means the cd needs to be serviced the re is no reset procedure ERR means th eunit has failed and needs service

This is the Radio Anti Theft feature which is activated whenever there is a complete power loss to the radio (as in when it is stolen out of the car). A Honda Tech or ASE Certified Auto Tech would have plugged in a Memory Minder into the OBDII slot to not only prevent this, but also protect the Main ECM from resetting which could create drivability issue.
If the Honda is now registered in your name, take it to your local Honda Dealer. They should be able to pull the Radio Serial number without removing it like in the older Hondas, simply a matter of pushing the right buttons. With the Radio Serial Number, Your Proof of Ownership (Registration) and a Photo ID that matches it, either the Parts Department Or Service should be able to give you a Radio Code for it.
As for the CD ERR codes, the CD player probably is broken and will need to be sent out by Honda to a outside facility to be repaired. That will probably run between $250 to $350, plus the labor cost to remove it and reinstall it.
If you just bought this Honda, or any vehicle, I always strongly recommend having a Manufacture Dealership do at least a oil change on it and check what other services may be due, you might also discover it has Recalls that have yet to be completed that they can take care of for you. Catch the little problems before they ruin that Great Deal you just got buying it.
Strongly suggest you also join Hondas “OwnersLink”, you can find it on the Honda web site under Owners Resources links. In the future you can use this to recover your Radio code after you’ve been registered for awhile. Also keeps you notified of Recalls, Service Issues and even sends out Discount coupons (Latest is a $119 trunk cargo trays for $39, that is a Fantastic Deal).
Good Luck

Sometimes disconnecting the battery for a few minutes,long enough to lose your presets for the radio stations, might reset the cd player.But it might be jamed or broken which would need replacement

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 had the same issue with the radio code error lock on a 2005 CRV. I was unaware of the code procedure and had locked the radio in the "ERROR E" mode. I was able to unlock the radio by pulling the #9 back up fuse located in the fuse box in the engine compartment. This reset the radio to CODE which then allowed me to input the 5 digit number which I had in my glove box along with my owner's manual. I am happy to report I now have a working radio/ CD player.

try disconnecting the battery for several minutes then reconnect this may act as a reset and bring the stereo back to its original state
