Honda Radio Pin Code
All I need is a serial number of the radio, to get it please follow instructions below
1. option
Turn the ignition switch ON,
Hold and press buttons 1 & 6 whilst turning your radio on,
Serial number will appear on screen.
2. option
Turn ignition switch ON,
When radio displays "CODE" on screen, turn radio OFF.
Press and hold top halves of the SEEK/SKIP and CH/DISC bars and then Press and release the PWR/VOL knob.
a 10 Digit serial number will appear on the screen.
3. option
If above two options didn't work or not available, then remove the radio and take a photo of the label attached to the radio unit.

All codes are generated within 5-10min, busy times or night time can take a bit longer.
Thank you
