Solar Digital Car Speedometer with Temperature Altitude plus Speeding Alarm

RYSJM Solar Digital GPS Head-Up Display (HUD) Speedometer – Wireless Car Speedometer with Temperature, Altitude & Safety Alarms

🚗 ☀️ The All-Vehicle Solar Dashboard Companion That Does It All Meet the RYSJM Solar Digital GPS HUD Speedometer—a feature-packed, zero-wiring dashboard display engineered to enhance driving safety and keep essential metrics right in your line of sight.

Combining an ultra-sensitive satellite GPS module with a integrated solar panel, smart vibration-sensing power management, and real-time environmental monitoring, this standalone HUD delivers instant ground speed, ambient temperatures, altitudes, and safety reminders. Because it operates 100% independently of your car's OBD-II computer, it works universally across all vehicle makes, models, classic cars, electric vehicles (EVs), and trucks worldwide.

☀️ Dual Solar & USB Hybrid Power Core

• Integrated High-Efficiency Solar Panel: Automatically absorbs sunlight on your dashboard to continually replenish the internal battery during daytime drives.

• USB Charging Cable Fallback: Includes a dedicated USB charging port for rapid refueling or extended nighttime driving. (Note: Solar charging is designed to extend battery life continuously; initial charges or low-sunlight conditions should use USB power).

• Smart Vibration-Induction Auto On/Off: Built-in motion sensors automatically wake the screen when your car starts moving and switch it off when parked to preserve energy.

🗺️ Comprehensive Real-Time Dashboard Metrics

• Multi-Metric Screen Array: Simultaneously displays real-time Vehicle Speed (km/h & mph), Clock/Time, Altitude, Ambient Car Temperature, and Battery Level.

• Automatic Adaptive Brightness: Features an intelligent light-sensing display that boosts contrast during bright daylight and softens output at night to prevent driver eye fatigue.

• Independent GPS Accuracy: Uses internal satellite telemetry to calculate ground speed directly, avoiding speed errors caused by modified tire sizes or gear ratios.

🚨 Dual Driver-Safety Alarm Systems

• Configurable Over-Speed Alarm: Set custom speed thresholds to trigger instant visual and audible alerts when you exceed local limits.

• Fatigue Driving Reminders: Automatically alerts drivers during long, uninterrupted journeys to encourage timely rest breaks.

• Manual Speed & Time Calibration: Includes manual adjustment menus to easily calibrate speed variances or fine-tune local time zones directly on the unit.

🛠️ Quick-Start Operating & Calibration Guide

1. Initial Signal Test Notice

The device uses internal GPS satellites to collect speed and time coordinates. Do not test the unit indoors or inside a garage, as signal reception will be blocked. Place the unit on your car dashboard outside under an open sky for 30–60 seconds to establish a strong satellite lock.

2. Manual Speed Calibration

If the HUD speed readout differs slightly from your factory dashboard:

1. Long-press the "SET" button to enter the configuration page.

2. Short-press the "SET" button every 3 seconds until the speed data area flashes.

3. Use the setting keys to adjust the speed value up or down to match your vehicle's exact speed.

3. Manual Time-Zone Calibration

If the time readout does not align with your local time zone upon acquiring satellites, enter the settings menu using the same long-press "SET" procedure to calibrate the hour display manually.

🛒 Real-Time Speed Precision. Solar-Powered Dashboard Safety.

The RYSJM Solar Digital GPS HUD Speedometer is the perfect upgrade for drivers wanting clear, eye-level speed monitoring, commuters keeping tabs on ambient temperatures, and long-distance drivers benefiting from fatigue reminders.
