Speedometer not too accurate? Older vehicle? Or just want speedometer to be mounted where it can be seen by other passengers?

Our GPS HUD units are used by the AA driving school instructors to make sure they are able to view accurate real time speeds during a lesson. Not only that, because the unit runs on purely GPS signals the speed is a lot more accurate than most speedometers which normally read lower.

The units come with a 3M windscreen mount tape, holder and a 3 metre long USB cable allowing you to connect into any USB power source in the vehicle. 

We also have hardwiring kits available here if you prefer to have everything hardwired by an auto electrician or yourself.
