Replace the USB cable for testing, and prohibit the use of voltages exceeding 5V. **Q: No speed** A: The flashing power satellite icon indicates satellite search status for underground parking garages, tunnels, and overpasses. When obstructions prevent satellite connection, move the vehicle to an open area to restore normal operation. **Q: After the vehicle stops, the speed will still be displayed.** A: Underground parking garages, tunnels, overpasses, and shielding may cause unstable signals and satellite drift. Please drive to an open area. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Inexpensive and useful *by R***E on 6 July 2025* ### ⭐⭐⭐⭐⭐ Heads up display. *by R***N on 24 February 2026* ### ⭐⭐⭐⭐⭐ Satisfied Customer *by K***. on 9 January 2026* --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/658198754-h4-car-hud-head-up-display-gps-speedometer-with-auto](https://www.desertcart.tn/products/658198754-h4-car-hud-head-up-display-gps-speedometer-with-auto) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-13*
