CHAMPLED 5.5 inch Car HUD Head Up Display OBD II Speeding Warning System Fuel Consumption Tw For HONDA INFINITI KIA HYNDAI DACIA DAEWOO

I will test this when i'm comming home.

Mph are so off its stupid. Going 60 and it tells me it's 72. Beeps non stop if I go over 70. Very disappointed. Wish I got the echoman hud instead. This had so much potential and really let me down. How is a Mph reading going to be THAT incorrect when it's plugged into an obd slot. Waste of money
