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 Tammy Finucci

The screen is absolutely accurate, RPM, TEMP, SPEED all reads great on my 98 Camry. I bought this device to keep track of my voltage and temperature, but the other sensors are a welcome addition and easy to pick and use. Screen size is good too, as the Camry doesn't have a lot of extra dashboard real estate. I mounted the screen directly to the stock tachometer on my dash, but I can still see all the other dash elements. Make sure to update the screen software, it's very simple, go to Joycarchina website, select Downloads and search for V70 installer, bypass the user control settings if you have WIN10 and install the tool. Connect the screen to the computer while holding OK and boom, you're now updated! Again I am very satisfied and would recommend it to anyone using OBD II and some slight mods on their car like me. and owners of OEM production vehicles.
