05 odyssey code error E come on my radio screen and the sound system doesnt work. What to do ??

Does the radio work at all. or is the cd player the only issue.? most of the time you need to enter a radio code to unlock the radio. If you enter it wrong to many times it will display error on the display.if you dont know the code then you can call the dealership and get the code after you do the following below to get the serial number.
Press and hold 1 and 6 on the radio while still holding the 1 and 6 press the power button. At this time it will read off serial number

Look on glove door for the code and press the numbers on the radio to fix

Folow the cable with a test lamp. When you get to the break the lamp does not work. We used an old side lamp bulb for testing as it drew about half an amp from the supply not like a volt meter.

You need to be very careful Each failed attempt causes a long delay before you can enter it again. Follow the instructions exactly. You may need to use the car for a day or more before attempting it again if you failed too many times. The radio should say CODE not ERROR. Error means no code can be entered now. You must wait until the radio displays CODE.

yes if you have the code and the display reads error then you need to reset the audio unit. to reset you can disconnect the neg and pos battery cables hold them so they are touching each other for approx 30 seconds. reinstall cables and the error message on the audio unit sounds be cleared and you can now enter you code. if it still reads error then there may be internal damage to the audio unit- hope this helps

you can easly do it you self u will just need a radio code to enter when u r all done so done forget to right down the numbers on the radio u r putting in and call ur local honda dealer for the code

with the 1 and 6 held down on your presets turn on your radio and it should display your serial number to your radio write all that down and call your honda dealership then you should be able to get your code

also try looking under the ash tray in your vehicle by pulling it out cause some companies put the code there

my code was on the inside of the glove compartment

go here this should help
