Features & Capabilities

ERC Calculator - Unlock Your Car Radio/Navigation System

This Chrome extension helps users regain access to car radios or navigation systems that have locked due to battery removal or power drain. By decoding the 16-character ERC code displayed on the device screen, the app allows you to unlock and restore all features such as FM/AM radio, CD player, TV, USB, DVD player, and more.

The extension guides you step-by-step to find the ERC number: hold the main button on your navigation device, cycle parking lights on/off 3-4 times to reveal the code screen, then retrieve the 16-digit serial number necessary to generate the unlock code. Note that this ERC number is different from the physical serial number found on the unit. This tool is essential for vehicle owners seeking to quickly and easily restore their multimedia system after battery interruptions.
