RYSJM support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I switch my RYSJM HUD between OBD and GPS modes?

    Within 5 seconds after powering on the device, short-press the select button to choose between the OBD or GPS system. If no selection is made, it will default to the last used system.

  • How do I adjust the speed on my RYSJM HUD if it doesn't match the dashboard?

    Enter the settings menu by long-pressing the 'M' button, navigate to the speed calibration setting (usually Item 1), and fine-tune the parameter value to offset the difference.

  • Why does my RYSJM Head-Up Display turn off repeatedly while driving?

    This usually happens if the vehicle's voltage reading is too low for the device threshold. Try adjusting the shutdown voltage in the settings menu (often Item 10 or 11) to 13.0V or 12.8V, or switch to a direct USB connection instead of OBD2.

  • Will the RYSJM OBD2 HUD work on my hybrid vehicle?

    Yes, but you may need to adjust the settings. Enter the system settings, locate the Vehicle Type Selection, and change the parameter from 0 (gasoline) to 1 to support hybrid or auto start-stop systems so the device does not falsely detect a vehicle shutdown at red lights.
