I have a 2004 Accord V6 with navigation system. Today when I started the car the screen for the nav system just started flickering black and white. We tried disconnecting the battery to reset it but the screen still just flickers. Now I can't even enter the code so I can get my radio/CDs/clock back because I don't have a screen that works to enter the code. Any suggestions? I taped a piece of paper over the screen right now because it was giving me a horrible headache to drive while seeing a flickering screen.

 

Try this first:
1. Turn the ignition switch ON (II)
2. Open the front cover of the navigation unit located in the trunk.
3. Press the EJECT button.
4. Remove DVD and then reinsert.

If no change, you might want to contact Alpine Electronics of America to see if they can help you. Explain your problem. If it turns out to be the Navigation Unit located in the trunk, they can fix it for a couple of hundred if you send it in.

The navigation unit located in the trunk (Honda part number 39540-SDA-405) through Honda is like $2,500 - $3,500, not including labor.
