Review on Advanced 5” FHD 1080P HUD Display for Car OBD2 Gauge: 3D Reflection, 6 Modes, ECU Data, and Fault Alarm by Johnathan Sherman

Works great, can be seen clearly in any light. There is no duplicate image you get on a HUD projected onto the windshield. We just did 600 miles and it was really helpful. The problems were only with the calibration. It's still a few mph, even after changes in +/-1 increments. -3 seems closest. Also not a fan of flat cable instead of round. This makes it difficult to slip unnoticed around the bends in the dashboard to the OBD port. I need to figure out the best way to hide the cable in the dash. Maybe it would look cleaner if it exited from the back instead of the side.
