How accurate is your speedometer

Do u really think a signal from a satellite is going to give u a better reading than ur car? Go to the track n use a laser. That should be a lot more accurate.

Yeah they are spot on! I've got two GPS units that both measure my speed identically. They are also spot on when approaching one of the "Your speed is" signs. ;-)

Again, you need to study up....

"Garmin's specifications quote 0.1mph accuracy but due to signal degredation problems, perhaps 0.5mph accuracy in typical automobile applications would be what you can count on."
