Cant enter code to acess cars audio system

Unfortunately 90% of the time when you get error codes from the CD player/changer it means that there is a mechanical failure in the CD player/changer unit itself and it usually requires CD player/changer rebuild or replacement...
First make sure you have entered the correct anti-theft code. If battery power has been disconnected recently than the stereo display will read CODE if the incorrect anti-theft code is entered the display will read ERR1 thru ERR3. If this is the case you'll have to get the correct anti-theft code. Note; If you enter the incorrect code three times the stereo locks up. Disconnect the battery for more than 30 seconds and then retry.
FYI;Never use adhesive labels or protective disc covers on recordable CD's. Recordable CD's are actually thicker than pre-recorded CD's. Automotive players and changers use rollers to draw the disc into the unit. The added thickness of an adhesive label or protective disc cover may cause the disc to jam. Also CD players and changers are exposed to high temperatures inside the vehicle. High temp will cause the labels adhesive to soften which may cause the labels edges to curl or cause it to bubble. Either one may cause the disc to jam. If the player can not be disassembled and have the discs removed successfully than it will have to be replaced. -hope this helps.

stereo codes for Honda

Method 1 (all applicable models except '03-07 Accords with the navigation system)
1. Turn the ignition switch to ON (II).
2. Turn on the audio unit, and make sure you see stereo COdE in the display. If you don't see this message, pull the backup fuse for 1 minute, and then go back to step 1.
3. Turn off the audio unit.
4. Press and hold the 1 and 6 preset buttons, then turn on the audio unit. The display toggles between two screens. The first screen displays a U and the first four digits of the serial number (for example, U2200). The second screen displays an L and the last four digits of the serial number (for example, L0055). Ignore the U and L, and write down all eight digits.

Method 2 ('03-07 Accords with the navigation system)
1. Turn the ignition switch to ACC (I).
2. Turn on the audio unit, and make sure you see COdE in the upper display. If you don't see this message, pull the backup fuse for 1 minute, and then go back to step 1.
3. Turn off the audio unit.
4. Press and hold the top halves of the SEEK/SKIP and CH/DISC bars, and then press and release the PWR/VOL knob. This display toggles between two screens. The first screen displays a U and the first four digits of the serial number (for example, U2200). The second screen displays an L and the last four digits of the serial number (for example, L0055). Ignore the U and L, and write down all eight digits.
5. Call Honda Dealer for Radio Code.
6. Use the TUNE knob to enter the first four digits of the anti-theft code into the audio unit. (Ignore the last digit; it's not used.) When you turn the TUNE knob, COdE disappears, and a single digit is displayed. Turn the knob left or right to select each of the anti-theft code digits. When you press the TUNE knob, the system beeps and accepts each digit as it spells out CODE on the display.

If this don't work, definitly you need to call Honda delaer using your VIN.

Hope this help.

If you replaced your battery, you probably lost your audio system code as well. You should put that in first or your navigation system voice will not work. I assume you have the code for your audio system.
After you get your audio system working then you should be able to put the code in for you navigation system as follows:
Enter the four-digit navigation system security code, then select Done. If you have entered it correctly, the display changes to the Disclaimer screen. You have ten chances to enter the correct code. If all ten are incorrect, turn the ignition to OFF, then back to ON (II) to have ten more chances to enter the correct code (I would try this is your unit has turned off and doesn't come back on).
If you have other questions on this, leave a comment and I will investigate further.
Hope this helps you.

Your car’s audio system will disable itself if it is disconnected from electrical power for any reason. To make it work again, you must enter a specific five-digit code in the Preset buttons. Because there are hundreds of number combinations possible from five digits, making the system work without knowing the exact code is nearly impossible.
You should have received a card with your manual(if you have one) that lists your audio system’s code number and serial number. If you don't have the card, you can get the code number from your Honda dealer, but to do this, you will need the system’s serial number, or maybe the accord's vin number.
You will see ‘‘Code’’ in the frequency display the next time you turn on the system. Use the Preset buttons to enter the five-digit code. If it is entered correctly, the radio will start playing.
This is probably the case. Hope this helps.

Disconnect your positive battery cable for several minuets - and try again..

hit it with a hammer ?¿? it might not have a number above six?? or you have to use the volume control or tuner or something.What i often do is to locate a main dealers then look for the nearest cafe to it and wait for some of the mechanics to come in for coffee and ask them .

You only get like 10 tries this means you made to many attempts trying to put the wrong code in. Disconnect the battery cable and then try putting the code in the radio again.

try cleaning the unit with a disc cleaner.and make sure all dvds are clean
