SinoTrack HUD GPS Speedometer Universal Car Heads-up Display 2.7inch MPH Speed Meter with Compass Over Speed Alarm for All Vehicle USB Connect Plug and Play

Exceptional product! The SinoTrack HUD is easy to install, accurate, and very useful. The display is clear and the compass is a great addition. Highly recommended!

Easy to set up very nice to use wish there was some kind of pod or something that it would set in to be able to put it on or use it with different vehicles

Works very well

Great GPS speedometer, I put it on a 1977 moped without speedometer. Bought this one because it's the only one on amazon that can be calibrated, after setting the calibration to 97 (three mph slower) it's spot on. But greatly lacks one thing... It has NO way of mounting accept a little sticky pad, so my solution was to very carefully drill a hole through the back and slip a zip-tie through and presto, easy mounting. The auto dimming is also a big plus to readability, but the setting menu is a little tricky. One last thing is it makes a very faint high frequency sound, which probably isn't even noticed by most people.

Works, but NO instructions and NO box..Didn't come with anyway to mount it either.There's rubber stuff on the cord, I assume it was a return..

I use GPS speedometers on my cars with metric ones, especially when they have different wheels or power trains than stock.This has a great display, but takes much longer to find satellites and show speed than the other brand I have in two cars.

These things are awsome for hot rods! I bought 3!

Everything about this little device is perfect and is exactly as described. It retains the memory of your settings, the compass is accurate, the speedometer is accurate (I had to tweak the value slightly below 100 in the settings to get it absolutely accurate) . It has numerous brightness options which is great. This exceeded my expectations, I highly recommend buying this
