Be aware this item lets out a very loud beep after 1 hour of driving which is to stop you nodding off at the wheel!!!

Scared the c**p out of me..thought I had engine fault!!!

All revealed if you read the instructions...but who does that !!!


Don't be fooled into thinking that GPS always gives an accurate speed readout in a car.

It will be accurate on the straight and level but less accurate on hilly and twisty roads.

Not with all GPS but many don't take height change in to account when calculating the speed.

Think basic trigonometry.
