Had to change the car battery. Made several attempts to key in the code to restart the radio with no success. Keeps reading error E. Any suggestions would be great
Thanks

Are you sure you are using the correct code? I've had many Hondas over the years and if I remember right that message appears with the wrong code.

Go to "https://radio-navicode.honda.com" and follow the instructions. You will need your VIN, the radio serial number ( I found an 8 digit number on a small white sticker on the side of my glove box), and your phone number and zip code. I entered all this info and instantly got a response. I was then able to turn my car on, enter the 5 digit code by using the numbered preset buttons and now I have my tunes back! Hope you've discovered this already but if not, hope this will work for you!

What if you don't have numbered preset buttons. I have navigation but no numbers on any buttons on my console.
