| Issue | Possible Cause | Potential Solution(s) | | :--- | :--- | :--- | | | USB drive not detected. | Ensure USB is FAT32-formatted. Try a different USB port. Use a smaller capacity drive (8GB/16GB). | | Update fails with signature verification error | Wrong firmware file. | Double-check your unit's System Information against the file. Download the file again. Try a different firmware version. | | After update, screen is black, but unit works | Wrong MCU or display driver in firmware. | This is a serious issue. You may need to source the correct firmware and flash using PC tools (e.g., SP Flash Tool). | | Physical buttons don't work after update | MCU data mismatch. | The metazone file (containing MCU/button mapping) is likely incorrect. You need to obtain the correct one for your specific car model. | | Audio is very low after update | Firmware uses different audio scaling. | Check audio settings (EQ, gain). As a last resort, flash an older firmware version that worked. | | Touch screen is reversed after factory reset | Touch screen panel type mismatch. | Access the touch screen calibration settings (usually found in Settings > Factory Settings with PIN 1234 or 8888 ). Recalibrate the touchscreen. | | Steering wheel controls don't work after update | CAN Bus decoder information is missing. | The CAN Bus protocol or decoder settings were likely wiped. Look for the CAN Bus configuration section in factory settings and select your vehicle's make and model. |
