3.5” Upgrade Heads Up Display Car HUD Display OBD2 GPS Dual Mode Speedometer Odometer Diagnostic Cleaner Display Altitude Flux Data Clock Alarm Overspeed Temperature Compatible for All Vehicles

beautiful design, doesn't do all that stuff! Direction, volts, rpm, tempersure, speed, directiontruly disappointed. firec t ions are marginal,I need to ride specs to see if I ordered wrong version or if it's overstated capabilities

This works good as a heads up speedometer but the directions are so confusing and poorly written I can’t figure out to get it to do anything else.

Si lo que quieres es tener información directamente en el parabrisas y así no necesitas desviar la vista de la carretera para ver el cuentakilómetros, bien. Sin embargo, las instrucciones son muy limitadas y aunque te manejes bien en inglés, a fecha no he sido capaz de sacarle todo el partido posible al aparato. Solo veo la velocidad (no muy exacta) y la brújula, lo demás tendré que meter mucho tiempo en descifrar.

Wasted 3hrs trying to get this to work as it is described but the so called "instructions" do not translate into English and do not make any sense. I looked up on the internet on how to install but couldn't find any instructions for this item. I got it to display the speed on the windscreen but not in MPH. I tried to follow the instructions on how to change it to MPH but I couldn't make any sense of it. Also, when I plugged in the USB cable and turned the engine on, smoke started to come out!!! I use the USB port regularly and have never had a problem before.Maybe this item does work but, they need to sort out the instructions. Also, I notice that another review says how confusing the instructions are and, the other reviewers only seem to use it for the speedometer. I am returning it. What a shame and am very disappointed.

I just love gadgets
