Heads Up Display with OBD2 GPS Dual System, P8 Car HUD Display OBD2 Gauge Display Speed Clock RPM can Installed Dashboard and A-Pillar Trim, Car Speedometer for Car for All Vehicle

This is a very simple OBD scanner that reads the information the computer is getting And display it on a very nice LED screen. I admit it has its quirks , Like sometikes staying powered on . but it also has an on and off switch if I’m really worried about it. It is extremely easy to use and navigate the screens. The supplied power cable is plenty long to reach to the OBD port and keep wires tucked away

First, I received an obviously used box. Over half the label had been cut off the tap had been torn open, stickers were placed over the product code. No mounting hardware or tape was included.Second, not all of the features or screens pictures are available or function. Several of the pictures screens do not exist and are not customizable to work the way pictures.Third, the boost pressure screen never registered anything, it stayed stuck at one reading no matter what.Fourth, the GPS speed is wildly inaccurate. It read 15 mph sitting still.This is total and complete garbage.

Every now and then it freezes or stops working. Need to unplug it for 10 seconds and plug it back in to make it work again.

Bought a used 2009 Accord, wanted to see what kind of gas mileage it got, the car gets poor gas mileage (relatively). First tank added up to 22mpg (rated 30) with 90% highway driving, still I wanted to try and improve it some, while also learning what the car likes (improving mileage). I've driven an hour with this so far, not a ton of hands on experience but for me personally, the real time MPG seems to be average matching my fill up. I also learned the car really likes 65mph vs 75mph which the display showed an increase of 3mpg. Not dramatic, but at one point I was behind an 18 wheeler and the display was reading high 20's low 30's.I really like the real time feedback (though it may be a little to real time) where it will fluctuate slightly 1-2 times per second, I would prefer more of a 1-2 second average personally but not a big deal. For me the speed was off, I went into the settings (there is an option for offset) and found out it showed 110% speed, and a +2mph increase, set to 100% and 0 increase. It was about 5mph off at 75 (according to my car, and my GPS). I plan to tune the car up some as it kinda needs it, I expect gas mileage will increase as well.This really fit my needs perfectly, I was originally under the impression it would only tell me how many gallons per hour my car was getting, wasn't super excited about that, but it would have been easy math (speed divided by gallons per hour) but once I set it to US measurements, it was showing MPG. Very happy for that, the included velcro strips are strong, adhesive as well, but it doesn't hold up to the sun in my area (will come undone) while at work and falls off the side pillar beside the windshield. I just have to stick it back up and it stays once the car has cooled down.I plan to use adhesive to adhere it long term if this becomes a long term issue, minor issue however. I bought this car, due to wanting something that got better gas mileage. While not amazing gas mileage I do believe this will help me get the most out of the $$ I put in the tank :)

I used this for my dodge magnum 2006 and it worked fine. Gives me the speed and battery charge as well as time and other things I was looking for. Good product and was smaller than I expected but works nonetheless.

It’s alright. It’s unresponsive for a few seconds then reverts to factory settings, values pretty inaccurate(my mechanical turbo gauge reads 16psi while device reads -.7psi at all times)viewing angle on display is very poor. Pretty sure I received a used unit.UPDATE: it just completely stopped working saying “vehicle doesn’t support OBDII” even after I was “working” a week ago. Over all trash

I bought this because the description stated that it provided the engine temperature. This is a lie. This didn’t read codes, it didn’t reflect engine temperature, it simply provides speed.
