Been caught speeding lately? Sick of getting points deducted? Tired of donating your money to the government money making scams that are termed "safety cameras"?

Tchart Development does not endorse driving at excessive speed but like many we have been nabbed going slightly over the speed limit. GPS Speed Sentry was developed to provide a subtle warning mechanism that you are exceeding the speed limit. This is particularly helpful on those long road trips when you should be watching the road and not your speedometer.

GPS Speed Sentry is a GPS enabled speed monitor/car computer. It monitors your current speed and warns you when you are near or go over one of 6 user defined speed limits. It also allows you to view other GPS derived information on a series of display types. Other information includes current/top/average speed, a trip meter, an odometer, elevation, position, bearing and much more.
