Reset Radio

When you replace the battery on your Honda, you may need to reenter the radio code. There is a couple of ways to get a Honda radio code.

1. Most Honda owners don’t realize that the radio code was written on a small card or at the beginning or end of the owner’s manual. So if you still have your owner’s manual, open it up and see if you notice a four to six-digit code.
2. Another option is to call your Honda dealer and provide them with the VIN. You can find your Honda at the left lower corner of the windshield or vehicle registration.
3. Visit https://radio-navicode.honda.com/ during working hours and input the data in the “Get Codes” tab. The website’s working hours are Monday through Friday 6 am to 11 pm (CDT), Saturdays 6 am to 8:30 pm (CDT), and Sundays from 6 am to 11 pm (CDT). You will be requested to provide your current number and zip code. They will also require an email address so your confirmation number can be sent to you for your records.
