Review on ACECAR HUD: Advanced Digital Speedometer With OBD2+GPS, Tachometer, ECU Data Display And Warning Function For Enhanced Driving Experience Across All Vehicles by Dorian Bharadwaj

Overall I like the Product its clear and easy to use. Only the 12 Volt connection is not explained and no Cigarette lighter Cable. So People which has no OBD input can not use this product the users manuel does not give any information for this.The other thing would have been good to able to scroll Backwards too, that is if you want to change the screen Display to show another information you must go through all the different information until you reach your required Display that I find quite annoying.
