Review on 🚗 Wiiyii P6 Car HUD Head Up Display: Ultimate OBD+GPS Smart Gauge for Unmatched Performance in Every Car by Jason King

That solved my problem! As you can see in the photo (taken from van driver's point of view), the top of my van's steering wheel blocks my view of my speedometer while driving. With a slight modification (a screw through the back of the bracket) I was able to install it using the existing dash hole. Now it's very easy to see my speed at a glance. I can also see the compass readings. Those were the only two data points that really mattered to me, but the display also shows engine temp (with graph) and altitude. There is a star deduction for the incomprehensible operation of the buttons. I just had to play around with it until the screen was how I wanted it lol. Powered by data port under dash. Starting the engine, automatic shutdown when not required. It was a great addition and a must-have when driving our Class A. Hope this helps someone!
