Locate the physical pinhole button on the front panel of the head unit.

If you are looking for specific technical help with your unit, could you tell me:

| Issue | Description | Potential Solutions | | :--- | :--- | :--- | | | System becomes noticeably laggy, often after attempting to install an Android 10 update. | This strongly indicates the unit has only 1GB of RAM. The only real solution is to re-flash the correct original firmware for your hardware. | | GPS Signal Loss (Satellite Drop) | Head unit frequently loses GPS lock and fails to re-establish it. | Install a repack with a modified gps.conf file. Replace the file on a rooted device or install a custom repack that includes the fix. | | Boot Loop (Stuck on Logo) | The head unit gets stuck in an endless restart cycle at the Android logo. | This is often caused by a failed update or incompatible modification. Try the RST (reset) button. The ultimate solution is to flash the full firmware using PhoenixSuit and an A-to-A USB cable. | | USB Port Not Reading | One of the USB ports does not recognize connected drives. | Test with a different USB port and ensure the device is formatted as FAT32 . Try cleaning the metal contact points. Avoid using very large capacity flash drives. | | Touchscreen Confusion | Touch inputs are not registering where they should, or the entire interface is rotated. | This can be caused by installing a firmware for the wrong screen resolution. It can sometimes be fixed by entering the factory settings (often password 1617 ) and correctly setting the LCD type and screen calibration. | | Camera Not Working | The rear-view camera fails to display an image after an update or reset. | This is often because camera settings were erased. If you have no backup of the original cameraparams file, restoring them can be challenging. A hard reset may help in some cases, but the only reliable fix is to manually set the correct parameters. | | YouTube/Google Play Issues | Errors like "YouTube version is outdated" or Google Play Services failing. | This can often be fixed by installing a community-provided update that refreshes Google Play Services and YouTube. |

The head unit will reboot into Android Recovery Mode. A progress bar will appear on the screen.
