2004 Honday Odyssey- the power outlet blew out then the radio/ entertainment system went to the anti theft mode. I have the code for the radio. Nothing or the word "code" doesn't show up on the screen. The negative battery cable was unhooked for 2 hours. When the battery cable reconnected, the word screen still didn't show up. I changed the fuse for the ACC socket which was blown out. The ACC socket still doesnt' work. Any ideas of things to check.

You have the wrong stereo code. No Honda stereo code has a 0.Your local dealership parts dept. should be able to supply the stereo code given the VIN of the vehicle or serial number of the stereo.

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

You must go through your local honda dealer, (usually parts department) give them the numbers off the labels on the radio, along with the VIN number of the car. may have to prove ownership. They can call Honda and get that information for you. Process is alot easier if you someone that works in the parts department, if not the honda parts department, then another parts department at another car dealer.
