OBD2 + GPS Dual System Head-Up Display with Navigation and Alarm Functions

Introduction

The RYSJM C1 Head-Up Display (HUD) is designed to project essential driving data onto your car's windshield, allowing drivers to view information such as speed, RPM, water temperature, voltage, and single mileage without diverting their eyes from the road. This enhances driving safety by keeping critical data within your line of sight. The C1 features a dual working system, combining both OBD2 and GPS modes, making it compatible with a wide range of vehicles.

Compatibility (Auto-match models, plug and play)

The C1 HUD is designed for plug-and-play operation with OBD or EUOBD (On-Board Automatic Diagnosis System) interfaces. It is primarily suitable for gasoline vehicles.

Compatibility Judgment Method:

  1. Open the hood and locate the OBD2 CERTIFILE sticker (as shown in Figure 1).
  2. Alternatively, check for an automobile diagnosis port under the steering wheel (as shown in Figure 2).

Note: U.S. cars manufactured after 2003 and most other cars manufactured after 2007 can typically use this device. However, some cars may still not be compatible. Please contact support if you have compatibility concerns.

Maintenance

Cleaning

Use the provided cleaning cloth to gently wipe the HUD screen and unit. Avoid using harsh chemicals or abrasive materials that could damage the optical coating or surface finish.

General Care

  • The HUD features an anti-reflective matte spray paint to prevent sunlight reflection and a thickened curved baffle for HD, no-ghosting display. Handle with care to maintain these features.
  • The fanless multi-position air cooling design uses a metal copper sheet for heat dissipation, ensuring high energy efficiency and reliability without noise.
