Head Up Display,ACECAR Universal Car Dual System HUD OBD2/GPS Smart Digital Meter Speedometer with Compass Test Brake Test Overspeed Alarm Fault Code Reader HD LCD Display for All Vehicle

I purchased this item back in early December 2019. I drive a 2005 Ford Excursion With the 6.0 Diesel. I had read online that the delta between ECT and EOT should not exceed 15 degrees farenheit. Most monitors have ECT. But only a few have oil temperature. This item claimed to measure oil temp. So I purchased it.When I first connected the monitor, I searched and searched and could not find a setting for EOT. After reading the instructions I found that Oil Temp is indicated as OIT rather than the standard EOT. This was my first clue something wasn’t quite on target.After running the truck several times with this monitor connected, it was indicating that OIT was running about 5 degrees cooler than ECT. This just should never be the case except when the truck is warming up. Once the truck is warmed up, Oil should always run hotter than coolant.I purchased another monitor which I knew measured EOT and found that indeed, the Oil Temp (OIT) indicated by this item is simply not accurate. I have no idea how they are determining this OIT temp, but it isn’t the true engine oil temp coming from the sensors and back through the obd2 port.There are many features I like about this item. Unfortunately it fell short for my use. I’ll still give it four stars because for many people, they will not need to measure oil temp. But beware if you do need EOT- this item is useless for this measurement.Also note, I don’t believe the mileage estimates are completely accurate either.

Edit #2 well now the product has failed miserably fell on its face doesn't even turn on anymore no bolt connection shown.Terrible quality now the window suction mount spring has magically broken and can't be put back together. Updated my review to now 1 star doesn't even deserve that to be honest. Quality control on these things is atrocious will not be buying from this company or seller again.Waste of money stay away Far awayEdit: Changed review and rating.Product works with GPS function on my car butbits not great nor wonderful by any means it's just basic. I still cant get my boost guage to work or the water temp. Those two functions are Intended for use of OBD port. Which does NOT work with my vehicle at all. As the review says below previously.For some reason or another I still like it and most of the feats the product offers but it's not ideal for everything I wanted it for in the first place which is the reason for 3 stars.Dead on ArrivalWould not turn on via OBD 2 port in my carI drive a Mercedes Benz 2019 C43 AMGThe OBD 2 port in the package is defective how do I know ?I work on cars all the time its literally missing 6 connector pins. This product is a joke. I am shaking the plug and can hear all sorts of moving parts from the Inside.Maybe the missing pins ?Wow so disappointed I shoukd have just kept the other guage looking Tech from this same company AceCar as that worked no issues. I just wanted the newest and greatest product but will not be ordering again. Seller will have 24 hours to respond to me send me out new unit as this one MUST GO BACK to the shelvesReturning

My 12 yrs old car has just passed 200k miles line and everything starts to fade away like a veteran. After one minor accident, all of a sudden, all the dash indicators stopped working that no speed and no rpm. It is a manual gear that I would need to know the rpm and also the speed in order to avoid the speeding ticket. The quote from the technician is way beyond the residual value of the car itself. Luckily, the OBD2 port still provides readings. I used an OBD reader at the beginning and it doesn't work well quite well until I found this gadget. With a small investment, I can the readings back without being ripped off by the auto shop. Can't be happier

The media could not be loaded.  I own the basic version of this unit as appears in my video and photos. This unit is a much extraordinary upgrade to the basic Acecar unit. It's small and light in my hand. I drive long commutes, day and night when I need to see my geographical directions, time and speed. This new unit gives me all this info in a simple way, plus a lot of other info as it appears in my video. I admire that this version saves a charging port of my car because it has an OBD cable, plus the usual mini USB cable. It can be fixed on the dashboard with a double adhesive tape (comes with an extra one) or the windshield by a suction cup. The unit is simply two devices in one unit, an OBD reader and a GPS meter. You can switch between both functions from the M button. I enjoy this upgraded unit because I can take it with me on traveling on any rental car, because of its suction cup.

Recently purchased this item when the instrument cluster on my car stopped working. It works well but I have not been able to figure out how I can get it to display the fuel level left in the tank. Anyone have a suggestion

This product is amazing most definitely would get another one if needed.

Thank you alot

I liked how it looks. The screen is bright and crisp. However, it's plague with the cheap Chinese components plague. Micro USB which is 20 years old. Reboots intermittently. When it works and it reading the car's ecu, it is slower than molasses in winter
