Car Scanner, ZYooh's X5 3'' OBD II Universal Car HUD Fuel icon Head Up LED Display MPH Speed Warning Black

hi this dr. vas here now a couple of months ago I did a review on a car head-up display called the 8/8 and after I posted that video the manufacturer of that unit contacted me and asked if I would be interested in doing a review on other models that they also manufacture and I said sure why not so I did receive two other head-up display unit in the mail recently the pamphlet that you're looking at shows the different models of head-up display units they manufacture now the last video that I did was on the aah this one right here with a 5.5 inch display now they sent me two models that they also make this is the q7 which is this one right here and the f6 and that's this unit right here now the q7 is an interesting unit because it uses GPS satellite to give you speed alerts speed reading through the power connection it can tell you the voltage of the vehicle so this one works a little dif
