Garmin speed indicator

[Udders]

Anyone know how accurate the "speedo" is on a Garmin 660? Is it likley to be more accurate than the bikes (or cars) speedo?

In a straight line, on level ground and at a steady speed, very accurate. However, if you're accelerating, braking, going up or down a steep hill or, possibly, going around a tight bend, the accuracy will be much less.
