Car HUD Heads Up Display 5.8 inch OBD Digital Speedometer Windshield Projector OBD2 Vehicle Speed Dashboard Display MPH, RPM, Fuel Consumption, Speed Alarm, Water Temperature, Voltage, Mileage

would not work with my car as I did not have a flat area suitable to mount it.

The HUD works perfectly, love the options. The user manual is very well organized in terms of the menu items, and how to correctly setup the HUD options. Easy to calibrate to indicate accurate speed and other information. Works great at night, and I can still read the speed during the day without reflective film.

Good sturdy product, it is at least 2 to 3 miles off from what the speedometer reads. The directions aren't very clear on how to correct it, so it just sits in my glove box now.

It didn’t work for My Mercury grand Marquis. Took a lot of work to figure out that it was not me. Instructions are terrible. Recommend spend more money.

The instructions are a bit difficult to understand if you are in a hurry but it's easy to figure out. Item works well when you convert to proper units and adjust.

The HUD is awesome.The only problem is that is drained my battery continuously.

Works great. Just a little adjustment to the speed which makes sense due to every car being different and works perfectly.

Total piece of crap the display was all upright and proper except the numbers showing speed the were upside down and mirrored and then by the time I got back to my house after noticing this it quit working at all I sent it back for refund after several months finally got a refund of $2 don't waist your time or money
