Windshield Speedometer Projector, Digital GPS Speedometer with Speed, Overspeed， Heads Up Display for Cars Suitable for All Vehicles

This is a good simple HUD unit that can display time, speed and compass direction using GPS. You just put it on your dashboard and let it reflect off the windshield. There is a film you can attach to the glass to make the reflection clearer. There are different display modes, letting you choose which elements are displayed.I've read that some people say that it is inaccurate. For me, the default settings made it display speed that was 10mph too fast past 50mph. I was able to adjust it so that it was within 1 or 2 mph from 0 to 65mph. Press and hold M to enter the menu. The first screen will show an adjustment value (I think default is 107 or something like that). Lower it to 102. Press and Hold M again to save and exit. That worked for me. The instructions are not very clear on that, but basically if it is showing too fast a speed compared to your speedometer, adjust that value downwards. If it is showing too low a speed, adjust it upwards.Limitations:1. It uses GPS, so it takes a moment to find the signal when you start the car.2. It uses GPS, so when you lose the signal (like in an underground parking) it will show 0mph.3. In bright sunlight, its projection can get washed out.4. If you wear polarized sunglasses, it may filter out the display as well.All in all, for the price, it's a good unit if you don't need anything fancy.

This is not the worst unit, but there are better... It is plug and play and easy to set up. However it's satellite dependent and not connected to vehicle for 100% accurate speed. The RPM gauge doesn't seem to follow at all, tried all settings. Instructions are very simple and provide little help... Like i said, it works and its too bad. Just wish it had a tilt capable to even out on window.. Do to the curve of my windshield it slightly tilted..

This was easy to install and I bought a hardwire kit so I could tap my fuse box and hide the install. Looks great, used 1/4 inch black plastic auto wire conduit (about 4 inches worth) to hide and protect the exposed wire on the dash area from direct sunlight damage and make it look clean. The unit comes on when I turn on my car and gets a satellite signal within 10 seconds so by the time I back out of my garage and drive to the end of my street it starts working. I had to follow the directions to fix the speed calibration and it is dead on the correct speed now. I have had it installed for about a month now and it is getting very hot here in the Dallas TX summer sun. It gets covered by my sun shade while it is parked at work.Not sure if this is due to heat but my wife and I took a drive out into the country a few days after I installed it. It did well for the first part of the 3 hour round trip but on the way back, it locked up on 0 mph and 7:00 and that did not change until I restarted the car after we had been back for about an hour. It did not do that again until yesterday when I was at lunch. I got back from lunch, turned the car off, went inside for about 2 hours then it did fine on the ride home, no issues. Not sure if this is heat related.I am able to see it without using the provided reflective static window cling used to reflect the light better during bright day light but I may try the cling soon to see if it helps during the day. Also, the unit has an auto dim for night use that helps a lot and looks nice. It looks the best at night or sun rise, sun set. The numbers for MPH are big and easy to see even without my glasses. I can also read the smaller clock without glasses. Its hard to see the compass and the timer numbers. Looks really good with my glasses on, very clear and looks very clean. Unit is black and very small and blends into my black dash.For the price its a nice little gadget but if I were to buy another I would get one that attaches to my OBD port and use the cars computer data to get speed and other info but also has a GPS to give a compass. Maybe $10 more.Nice little gadget. Easy way to make an older car feel a little more up to date and a newer base trim level car feel a little more luxury.

Excellent wow 😮

I don’t want to say this item is terrible, it’s not. There were just a few things I thought can be better. I wish the device were cordless. Also, the speed was about 10 to 15 mph slower ( I think that can be adjusted) but I would still need to deal with the annoying cord. Lastly, the design can be a bit sleeker more low profile.

The media could not be loaded. This unit is pretty much a plug and play type of accessory, and once adjusted is extremely accurate and enhances every drive.Initially the HUD was off between one and a half and two miles an hour as compared to my speedometer; with my speedo reading 50 mph the unit was showing 52 mph. After looking at the almost incomprehensible 'instructions' I was ready to leave it that way. Every BMW I've owned has been similarly optimistic, and you get used to it. But it was a rare top down winter day in Michigan - 66 degrees in February - and I wasn't in any rush to get home and park the car. So I drove a bit, stopped and made an adjustment, then repeated that two more times. In less than 10 minutes my speedometer and the HUD were dead on.I chose not to utilize the piece of plastic film provided with the HUD to increase the contrast of the readout, because I can see the reflection in my windshield fine without it, though it is less obvious in the daylight than at night as seen in my video. While the factory HUD in previous vehicles was more or less directly in front of the driver, I chose to locate this one almost in the center so my dashcam picks it up without any distortion, but that's a personal choice. If you appreciate having a simple HUD, this is an excellent choice.

So I got it today, I went to install it in my Rouge and it looked awesome. But trying to go through the manual set up, I realized the base did not stick to my dash even though I just cleaned it.I never got a chance to actually use it because my dash is bumpy and the adhesive just did not adhere to it.Might work great for a different model, but did not work for mine.
