AZIJYV H2 Digital Speedometer GPS HUD，Car Head Up Display with Speed Compass MPH ，Plug and Play Universal All Cars

Works great to see MPH on a car that is km easy to read at night and while driving

Awesome product. I have purchased 3 of these for all of my vehicles. They are super accurate. I actually bought these because I was searching for a compass for the car and stumbled on this. I bought it loved it and bought another and today just bought another.

This thing is great, if your speedometer doesn't work or is not correct, this is for you. I have had it in my offroad jeep for 2 years and it has never failed. For the cost, yoi can't beat it.

Works really well, sometimes takes a minute to come on, but it's accurate, the display is easy to read and it's bright enough to be seen in the dark but not be too bright

This digital speedometer has a strong GPS receiver (works places that usually have no or weak GPS signal). Has a easy to see display as well as compass and at a good price compared to others....

Installed as per directions. Turned on and waited several minutes for it to connect to the GPS satellite, only 2 white arrows in middle of screen with a blue band going around the edge of the screen face. Un plugged power cord and did a reset to factory settings, drove car around and about 20 minutes later it started working! left gps own for about an hour got back into car drove back home never came back on! I should have read reviews and picked a different one. Returning this GPS and ordered a different brand!

Great product

Easy to use, small but yet big enough to see clearly. Set up is a snap.

Does not work in the city. Works only where the device can have a clear uninterrupted view of the sky with no trees or buildings blocking access to satellites. Not worth the expense if you live in a built up city scape.
