If the corner colors of your GMC LED emblem are not changing, it is likely due to the pixel settings in the app. To fix this, open the app and increase the "Total Pixel Count" (点数和灯珠总数) from 55 to 105. This will ensure the signal reaches the entire emblem.
To solve the color issue on the corners of your emblem, please follow these steps:
- Open the control app.
- Locate the setting for "Total Pixels/LED Count" (点数和灯珠总数).
- Change the value from 55 to 105.
- Save the settings, and the corners should now change color correctly.
To find the Total Pixel Count, you can check the following settings:
📱 App Control and Setup: Using ZENGGE
The 2nd Generation emblem uses a dedicated application for control.
App Download
The control app, named ZENGGE, is available for both iOS and Android platforms and can be downloaded directly from your respective app store.


First-Time Connection (Crucial Step)
To ensure a successful connection between your phone and the LED emblem:
- Power On: Confirm your new LED emblem is installed and receiving power (i.e., the lights are turned on).
- Enable Bluetooth: You must have your phone's Bluetooth turned ON before opening the app. If Bluetooth is disabled, the app cannot detect or connect to the LED emblem.
Once connected, you will be able to customize your settings immediately. Please refer to the attached photo for a guide on the initial setup screen within the ZENGGE app.
