Review on Pyle PHUD18OBD Universal Car HUD Head-Up Display: 5.5’’ Windshield Screen Projector for Vehicle Speed, Diagnostics, Water Temp, Voltage, Fuel Indications & More! Plug & Play OBD2/EUOBD Compatible by Kyle Hoes

I bought this, installed it and was initially satisfied. One morning before work I woke up with a dead battery. I had to jump out of the car twice (once to get to work and once to get home). Then I charged the battery overnight. Lasted a few days and died again. Took it to the dealer and they couldn't find anything wrong other than a dead cell in the battery. I thought everything was ready, but less than a week later the battery was dead again. I took it straight to the dealer and they kept it for almost a week to figure out the problem. Remember I disabled the HUD before entering. They plugged it back in and the battery died overnight. I've left it disabled since then and there haven't been any battery issues since.
