RadioCode Opel/GM instantly finds your car radio's unlock code, starting from just the radio's serial number.
HOW IT WORKS
• Find the radio serial on the label stuck to its housing (pull the radio out of the dash with DIN removal keys) — it starts with GM or OP, 14 characters long.
• Enter the serial in the app and tap "Verify Serial".
• If the serial is found, reveal the 4-digit unlock code and enter it in the radio.
