1. LVDS Cable: Ensure the LVDS cable is connected correctly according to the schematic. The LVDS connection MUST be routed to the main head unit (host), NOT the transfer screen.
2. Pin Check: Unplug the LCD cables and check if any pins inside the ports are bent or not making proper contact.
3. DIP Switches: Verify that the DIP switch settings on the module box perfectly match your vehicle model according to the manual. (Note: Always keep the power ON when changing DIP switch settings).
4. If everything is correct and the issue persists, please contact our support team.

Q: What precautions should I take during installation?

A:

• Always Power Off: Ensure your car is completely turned off before disconnecting or connecting any wiring harnesses.
• Test Before Reassembly: After plugging everything in, lock the car for a few minutes, then start it to test all functions (sound, display, steering wheel buttons). Do not reassemble the dashboard panels until you confirm everything works perfectly!
