Car HUD Head Up Display P6, OBD+GPS Smart Gauge, Works Great for Most Cars

Plug and play installation. Plugged this into my car's OBD II plug and it came to life. Didn't need to change any settings. It immediately displayed MPH, coolant temp in farenheit, engine RPM and battery voltage. GPS speedometer is spot-on!

It is a good item to have and it is easy to used and it is very accurate and the battery life is very good and it fast and it will save u a engine in the long term

The media could not be loaded. Seemed good at first, but after a month of using it on my truck when I start the vehicle the gauge will emit a ear piercing alarm and the buttons have no effect to silence them. The only way to get it to stop is to unplug the OBD2 cable. I reached out to support and they gave me the run around and wanted a video. I'm attaching the video I captured but you shouldn't have to do so much back and forth to warranty a $30 item. They should have just replaced it when I first brought it up instead of making me message them back and forth multiple times. Complete waste of time. It's a neat concept when it works.

Useful if your instrument cluster has gone bad and you don’t want to spend hundreds fixing it or replacing it. The downside is, the temperature gauge portion of it does not work. There was something else that doesn’t work but I can’t remember right now. The speed monitor works flawlessly, the battery voltage reader works flawlessly, the trip advisor works flawlessly. 4 out of 5 stars from me. I believe it is worth the buy.

Easy to install and good quality ✅

I am only giving this three stars because I had to send back the first one because it does not read the mpg right. The new one I received also does not give the correct mpg. I kept it because I didn't want to deal with sending it back again. It gives a good reading on the engine temperature, has accurate reading for rpm and mph. It is also has good screen options and lights up nice in the dark. Also I like the style of it. The suction cup works well with no issues of it coming off the window. The wire tucks nicely out of site. I am just disappointed the mpg doesn't work right.

Well this is my honest review. I was a little leery of buying this product because it said frequently returned. I received my package today installed in my car and it works perfectly. You have to be willing to mess with the settings to get it just right the way you want it. I think that's where most of the confusion is coming from. So if you've got half a brain and are somewhat mechanically inclined you shouldn't have problem using this device. I like the fact that it gives me my oil temp and also my coolant temp among many many other things. It also works as an OBD2 monitor you can read and erase codes. I installed the suction cup on my window and the bottom part I put the sticky pad so I used both and the damn thing don't go nowhere. So I'm very happy with it I won't be returning it unless it breaks within 30 days which I don't foresee. Anyway good luck to you with your purchase.

Wow, great collection of gauges and DTC scan tool itself is well worth the money.The DIGITAL dashboard showing the speedometer/rpm looks cool and modern.The HUD secondary gauge displays Coolant and Oil temp, Voltage, MPG, etc.The display is bright and comfortably clear in bright daylight under the California sun.Installation was simple, plug into the OBD port, then run the cable to the top of the steering wheel.The cable was extra long (about 6 feet) and I stuffed the slack into the fuse box above the OBD port.The included manual covers basic setup but honestly you can figure it out with only 3 buttons to work with.It took me 10 minutes to set the IMPERIAL units (MPH, MPG), set the time (UTC -8 hours), set the auto-turnoff volage to 13.2 volts, and the secondary gauges.For accurate MPG for my car, in the Fuel Settings, I set the Model to Honda and "Swept Volume" from 1.6 liters to 2.4 liters.My car is showing 28 MPG which seems correct.The latest firmware seems to have fixed the complaints found in user reviews.Among them that I found are listed below for those that are on the fence.1. The "third display in the secondary gauges section" (which shows voltage) can be changed (yes all 3 can be changed now).2. The display can be set to IMPERIAL (MPH, MPG, etc) or METRIC (KPH, liters/100 km, etc) in the Settings menu.3. SPEED and RPM correctly matched the dashboard Analog gauges at freeway speeds for my 99 Honda Accord.4. Clock time is accurate after adjusting the TIME OFFSET -8 hours in the Settings (time is auto-synched with GPS which is a plus).5. No suction cup included in my package. I do not use it as it falls off unexpectedly during driving but incase you need it.6. OBD cable is high quality and fits very firmly into the OBD port. Unplugging requires force and it will not unplug while driving on the road.6. I wear polarized sunglass and can see the display crisp and clear in bright daylight. The display goes dark if you tilt your head 45 degrees.7. Car parked for 2 days with HUD plugged in and the car starts up fine. HUD kept all my settings. Manufacturer does recommend unplugging the HUD if car is parked for 7 days.8. For accurate MPG for your car, go into the Fuel Settings, set the Model (ie Honda) and "swept volume" from 1.6 liters to your engine size.
