NHZN W61G ERC Code Calculation Guide (Android & iOS App)
Hi!
Here is a simple guide to calculate the ERC code for the NHZN W61G audio/navigation unit.
To view your serial number, press and hold the main button on the unit while switching the parking lights on and off a few times.
A service screen will appear showing the 16-digit serial number.
Enter that serial number into our Android or iOS app to calculate the corresponding ERC code:

iOS: https://apps.apple.com/us/app/erc-unl...
After entering the ERC code into your unit, its normal functions (radio, navigation, Bluetooth, etc.) will resume.
