How to Fix Common Issues with Dingwei Car Infotainment Systems: Forced Upgrade Methods

 If you're using a Dingwei car infotainment system, you might occasionally run into issues such as:

• The system getting stuck on the startup logo screen (e.g., FIAT logo)

• Black screen freezes

• Clicking on “System Upgrade” does not work

To resolve these issues, here are two forced upgrade methods. Please note: The upgrade steps are the same across all platforms, but the system files must match the specific platform. Always ensure that you're using the correct upgrade package for your system.

✅ Method 1: Forced Upgrade by Grounding the Key Line

This method is for when the system is completely unresponsive, or clicking the upgrade button has no effect.

Steps:

1. Prepare the Upgrade Files
   Unzip the system upgrade package and copy all the files to the root directory of a USB drive or SD card.

2. Insert the Storage Device
   Insert the USB drive or SD card into the infotainment system.

3. Power Off the System
   Completely power off the system (disconnect B+ and ACC at the same time).

4. Ground the Key Line
   Connect the Key1 or Key2 wire (either one) from the power wire to ground.

5. Power On the System
   Restore power by reconnecting B+ and ACC simultaneously.

6. Release the Key Line
   Once the system screen shows the upgrade prompt, release the key line.

7. Wait for the Upgrade
   The system will automatically begin the upgrade. Once completed, the system will reboot automatically.

✅ Method 2: Forced Upgrade Using the Reset Button

This method allows users to upgrade the system directly in the car without needing to disconnect wires.

Steps:

1. Prepare the Upgrade Files
   Unzip the system upgrade package and copy all the files to the root directory of a USB drive or SD card, then insert it into the infotainment system.

2. Reset the System
   With the system powered on, use a small object (like a pin) to press the reset button on the infotainment unit.

3. Turn Off the System Immediately
   As soon as the car brand logo (e.g., FIAT) appears on the screen, immediately turn off the ignition or remove the key.

4. Wait and Power On Again
   Wait for 5-10 seconds, then turn the system back on. The system will automatically detect the upgrade files and enter the upgrade mode. Once the upgrade is complete, the system will reboot automatically.
