Review on 🚗 YUGUANG 4" Car HUD Display with OBD2 GPS Dual System - RPM, OverSpeed Warning, Turbine Pressure & More by Andre Tenk

Got this for my Chevy Truck. I put on bigger tires so the speedometer is several miles per hour behind. I thought GPS would be useful. Unfortunately, this device doesn't read my RPM, the fuel consumption can't be changed to gallons (imperial units) and the PID info doesn't work at all. I have the same results. The most frustrating thing is that it stays on all the time. Regardless of which mode you set (0,1 or 2), when the key is off, the device continues to work. This draws attention or drains the battery. Holding the right button (as suggested in the "manual") does not work. It just shrinks the display to a level where only the voltage display is shown. This will also draw attention or drain your battery. Looks great. Wish it was better ) mount bracket on a high angle windshield, but you could work around that. If that was the only problem I would leave it as it is.
