GPS Question

Help me.

I have a Garmon GPS. No matter what car I drive (we have a Boxster, Jeep Libertry and Toyota Sienna), the GPS speed is always 2-3 miles per hour slower that the speedometer.

speedometers overestimate - it's by design so they can't be liable should you get a ticket...

Now, now, don't get all cynical and say "but they should just calibrate it correctly"... with our nanny state these days, that's not an option b/c as you know, someone else always need to be held accountable for the wrongful actions of others
