Digital GPS Speedometer, HUD Head Up Display for Car, Upgraded 5.5" Large-Screen, Suitable for All Vehicles

I have a 1993 GMC Jimmy and it is hard to see the factory speedometer, this mounted right over it and I can still see gas gauge,water temp ,amp gauge. It has so many features I really like compass and attitude, the suction cup mount has not came loose even tho it is stuck to a slightly curved surface,plugged the USB power supply into my radio and it comes on when switch is on and off when the switch is off. That made installing it extra easy., I have had it a couple months now and no problem s at all. And the speed alarms help keep me from speeding . I have one set at 35 mph for city,one at to mph for the rd I live on and one set at 65 mph for interstate 85 that I travel often

Really adds a modern flare to my 30+ year old Dodge van, who's speedometers get really squirrelly after about 25 years. This works well enough not to get a speeding ticket and it has an adjustable overspeed alarm which keeps me from driving too fast on the interstate in my Maxivan (which are known killers of fast drivers).

It works well, but is a couple miles an hour off.You can scroll through different view options but they don't provide a view that I would like to see of it's available options. In other words, of the things that you can see on the screen there are only preset options instead of you getting to choose which options you see.

I have a Jeep Wrangler Rubicon with a small and nearly un-readable speedometer. I wanted something I could see and read that wouldn't break the bank. I ordered the Wiiyii HUD-G10 unit with some doubt that it would do what I need.Installiation was simple and the windshield mount was exactly what I needed. I drove around for about 20 minutes and observed that the unit is VERY readable in all light conditions. I was able to see and maintain numerous satellites and got a read-out of my speed and compass direction. I noticed the speed was about 2 MPH above my digital speedomemter reading. I followed the included instructions and adjusted the speed setting. I was able to sync my vehicle digital speed excatly with the Wiiyii speed display. I then corrected the time setting and was very pleased that I could easily see my speed, direction of travel and time. I then disconnected the unit and hoped it would retain my settings. After 10 minutes or so, I reconnected and was pleasantly surprised to see everything still set the way I wanted it.This was a VERY good purchase and low cost solution to have my speed and information where I could easily monitor it while driving. I would recommend this unit to someone that needs an inexpensive solution to a small speedomemter display.

Looks nice. Setup is ok but could be a bit better. Mine is off by 5mph. No matter what I do its consistently off.10/23/24 UPDATEThing has already completely stopped working. Changed cords, tried a phone charging brick, even cut the wire to hot wire it straight to my 12V....NOTHING!!!DONT WASTE YOUR MONEY!!!

Mounted this on my motorcycle, But the only mount Is suction cup. The second time I used it, I broke the simple slot on the back of the device that connects to the section cap, So now it's Velcro'd in place.Very bright and easy to see in daylight, but no dimmer. As stated above, it connected to satellite easily but ran exactly 5 mph fast said any speed over 10 miles an hour

I’ve had this for a couple months& it’s been working perfectly! & it’s accurate.

You can't switch it between MPH or the other one, I tried for 2 days to switch it, with no help from the instructions or video they provided, which was worthless and with the written instructions, both worthless, I took it off my windshield and stuffed in my center console, the hell with it, waste of money and waste of time don't bother.
