About
Locked out of your car's factory navigation head unit after a battery
disconnect? New ERC Unlocker calculates the correct unlock password
from your 16-digit ERC (Error Return Code) serial — fast, reliable,
and works directly from your phone.
HOW IT WORKS
1. On your head unit, press and hold MAP / MENU, then toggle the
parking lights ON/OFF 3–4 times. The 16-digit ERC serial appears.
2. Open the app, select your head unit model, and enter the serial.
3. Receive your unlock password instantly.
4. Enter the password on the head unit keypad to restore access.
