Trip Meter Accuracy - Impressed


I went to Pensacola, FL from Atlanta and I cleared out the trip meter in the GPS and the trip meter in my truck and I was surprised on the accuracy of the trip meter of the GPS verses the vehicle. Over the 400 mile journey there was a 1 mile difference between the GPS & truck trip meter.

Garmin nuvi 2455LMT (wife uses nuvi 255w) (sold C330)

WHat is funny

What is funny is that the truck meter is prob the one off. ...JK that is cool i will have to try that. The mph gauge seems to work better than the car though. Some cars read mph wrong and are off 1 mph per 20 to 30 mph. That is cool to know. Thanks.

Motorcycle speedometers are

Motorcycle speedometers are generally about 10% optimistic.

The speedometer in my BMW (1 yr old) reads 9% higher than the Garmin C530, and the odometer reads about 3% higher. I'm trying to figure out which one is likely to be the more accurate (I'm betting on the Garmin, but not certain), as I am leasing the Beemer, and, of course, the cost at the end is based on mileage over a certain limit.
