Seems to work well on Mustang Mach E
This was the second HUD I tried for my Mustang Mach E 2025. The first one would not run continuous power. This one works fine. I only am using it for speed and it seems to be accurate within 1 mph.

A must for any car
Replaced my navdy with this. Can adjust speed offset, great features Edit 10/5/2025 a second unit I bought does not wake on ignition. If I unplug from obd connector it powers up. I did a factory reset , and adjusted sleep voltage to 12.8, didn’t help. I verified voltage on obd and it’s 14 to 15 volts. So the only way I can use is to unplug and plug back in. Probably defective, lowering by 1 star

Easy to install
Easy to install. Easy to hide the wire. Accurate to 50mph then it’s a couple miles per hour above the dash speedometer. Close enough.

So far, so good, works as advertised
So far, so good after a few months. My daughter likes the HUD view.

Mostly good, sometimes screen dims
Mostly works good, but it will need some adjustment to read your speed correctly. The screen is mostly clear, but sometimes it will get very dim, not sure if its hot weather or what. Pretty easy to install and route the wires

Not too bad
Little skeptical on the adhesive because it's not too sticky, probably better with a flat dash, so I'm waiting for it to roll off. Gps seems pretty accurate. Clear visibility with slight reflection of the base of unit. Easy to install, plug n play.

Lots of parallax, the display completely vanishes in any bright light, and the words could not be made to match no matter what.
