Resetting the radio in your Honda is usually as simple as pressing a couple of buttons, but in rare cases you may need to enter a security code to regain operation of the radio.
Syncing the Radio
Turn the ignition key to the “On” position, but don’t start the engine.
Turn the radio on by pressing in on the volume control knob. After 10 seconds, turn the radio off.
Press and hold the power button for two to five seconds and watch the radio display.
