High end systems are generaly hooked upto the cars tachometer and take your speed from that.Deadmanwalking said:Thank you mr.bastard.
That was my original point. And also why i asked what make/model GPS system you had. As very high end systems are obviously alot more accurate.
A good installer will calibrate the GPS system better then the cars dashboard will show it and thus gps is precived to have a more accurate mesurement while in reality it is only interpreting the data provided by the car better
