Review on ACECAR Digital OBD2/EUOBD Speedometer HUD For Vehicles Post-2008, Plug And Play Head-Up Display With KM/H MPH Vehicle Speed, RPM, Clock, OverSpeed Warning For Enhanced Driving Experience by Michael Keegan

Intuitive and Easy to Understand - The tachometer and speedometer analog displays have a pointer that moves to indicate values, so you can visually identify engine RPM values and speeds. The digital speed readout is easy to see at a glance, so you can concentrate on driving without looking down, avoiding distractions and even accidents caused by looking down at the dashboard. Some can also display various values such as speed, boost, water and oil temperature, and voltage.
