I have a 2005 Accord Ex L with navigation. My battery died and navigation screen no longer works. I entered code and radio works. Navigation screen just shows a flickering light. How do i fix this problem?

DOES SYSTEM INTAKE CODE YOU TYPE AND RETURN WITH ERROR MESSAGE OR JUST PLAIN HAS LOCKED SCREEN? SYSTEM IS DESIGNED SO THAT IF INCORRECT CODE IS INPUT MORE THAN THREE TIMES SYTEM LOCKS ITSELF.WHICH REQUIRES THAN THE NAVI UNIT BE UNPLUGGED FROM BATTERY POWER FOR ABOUT 5-10 MINS TO RESET ITSELF.NOW INCORRECT CODE CAN BE DUE TO WRONG CODE/SERIAL # CARD FOR VEHICLE, UNIT HAS BEEN REPLACED IN PAST POSSIBLY AND YOU ARE INPUTING CODE FROM OLD UNIT UNKNOWINGLY. YOU ALSO WANT TO MAKE SURE CODE YOU ARE TRYING TO INPUT IS FOR NAVI-SYSTEM AND NOT THE RADIO CODE FOR THE STEREO. IF ALL ABOVE CHECKS OK THEN NEXT STEP WOULD BE TO REMOVE UNIT TO RETRIEVE SERIAL NUMBER FROM BACK OF NAVI UNIT THEN GO TO NEAREST DEALARSHIP WHO CAN THAN RUN S/N THROUGH HONDA IN SYSTEM AND RETRIEVE CORRECT CODE FOR THAN SERIAL NUMBER. LET ME KNOW HOW IT GO'S

I've reads post here suggesting disconnecting the battery for one hour. Couldn't hurt to try it.

Also try ejecting the Navi Disk, inspecting it for any damage, wait a few minutes and reinserting. The disk contains not only the navigation Database, but also part of the operating system.

DO NOT TRY INSERTING A OLDER NAVI DISK OR ONE FROM ANOTHER VEHICLE, THAT COULD DESTROY THE NAVI UNIT!!

If you need a new Honda Navi Disk, order it direct at https://www.hondanavi.com/Hondadvdsales/naviorder.php

Good Luck

Pull the radio out, take it to the dealer with your registration and ID. They will be able to get the reset code for you.

You could take the car to a dealer(Ali Bhai Motors in Karachi) who has the software disc to reinstall. I had a some what similar problem when I was changing the battery and the screen died

No-one is ever particularly happy to here this, but this is the way it is; we do have to keep in mind that the original idea of codes on radios was to prevent people who steal them from being able to use them.

So, if an audio unit with theft protection is disconnected from electrical power, you must enter a unique code number into the unit or it will not work. This code and the audio unit’s serial number are listed on the anti-theft ID card that comes with the vehicle. If this card is lost, you must obtain the audio unit serial number in order to get the radio code (some people say that they have found the code on a sticker inside the glove compartment, but I wouldn’t count on that). Some newer vehicles allow you to retrieve the audio unit serial number electronically from the radio. Refer to your owner’s manual for the specific procedure (the following usually will work: Turn the radio off. Push the preset 1, preset 6, and power buttons at the same time, then quickly release. The serial number will come up in two sets of numbers.)
Some older vehicles (model year 2003 and older) require a visit to the dealer in order to retrieve the audio unit serial number (or you can remove the unit and get the serial number from the back of the radio). Once you have the audio unit serial number, you can call Auto Customer Service at (800) 999-1009 or have the dealer look up the radio code.

Here is the URL for the Honda Owner page. If you register (no charge) you are able to get radio codes using the VIN number of your car, the serial number of your radio, and the Phone Number and Zip Code that you give them when you register.

Hope this helps you with the process.
