Review on 🚗 VJOYCAR V70 OBD2 Gauge HUD Heads Up Display for Cars - Car Computer OBD ii Scanner: Speed, Engine Coolant Temperature, Fuel Consumption, Digital Speedometer, Mileage, Overspeed, Voltage & Faulty Code Alarms by Melissa Hall

This item is very easy to install and easy to read. The transition from MPH to KPH is very easy. The display is clear and understandable. The instructions are very simple, but there are few details on how the device works. It would also be nice if the online guides were better. Overall I would give 5 if the documentation was better. After using the device! ***UPDATE*** I've been using this for a while and I'm really impressed. Excellent communication with the seller and updating the software. After completion, I was able to switch all views to functions that were important to me. The display is very clear and easy to read. The ability to change the items displayed is only limited by the sheer amount of data this device reads from your vehicle. I'm hesitating between 4 and 5 stars depending on my experience with the device and the support!
