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

Muito bom!!

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.

I purchased this for my 2nd Vehicle that is mainly used by my son. Now I like driving the 2nd car more probably because of this little gem! I like this much better than the window reflection type I installed on my 1st Vehicle. This unit lets you see your speed quickly and easily without taking your eyes off the road. It auto dims when the ambient light is low and I don't have any issues with glare. I like that it has a great deal of customizable settings. For instance. I have the over speed setting set to flash rather than beep, and it is set to the speed I want it. All and all, this is a great device for a great price. I will likely get one for my other vehicle!

Very good for the price you pay. I would consider using a better USB cord though because it ripped overtime

This GPS works very good and is very accurate. This was a very good buy and I am not disappointed with it. It has a big face, but I would say, it's the best size for my pontoon boat.
