What page is the code to program the radio on in the owners guide

It's usually on the top of the radio (read: must remove the center console, not common but it HAS happened) or hidden in the glovebox on Honda. However, if both fail refer to this: https://radio-navicode.honda.com/

If the radio isn't original to the car, the default code is hardcoded. In those cases, you need to take the center console apart for it, and write that code down in a safe place. If it isn't on the radio you'll need to find someone who can get the code and provide it, or replace the radio.
