It draws zero power when inactive, protecting your battery while ensuring the device is ready every time you drive
True 10Hz Refresh Rate for Real-Time Performance: Many imitations use low-end chips, but our GPS HUD features a genuine 10Hz high-refresh-rate chipset. Get real-time speed updates with only 1%-5% variance from your dashboard. Note: Initial GPS lock takes 10–30 seconds; not recommended for tunnels or underground garages
