Morning, Mark. I understand what your saying but I'm not sure the NAVI *might* not be closer.
Reasoning: (1) Navi appears to figure mileage via GPS - it always says a bit more in mileage than the odo. I tested it with my Garmin GPS, and the Navi and Garmin were the same - the odo differed. So, where does you opinion lie with the accuracy of GPS - many people differ, but my opinion (limited, though it is) from what I've read is that the GPS is more accurate. There are speed discrepancies in speedometers - that's undeniable - which would seem to affect the accuracy of the odo. Also, tread depth, to a slight degree, and how many turns you make. Some have changed tires and/or wheels - are they *exact*? (2) Has anyone seen the reports that are issued on the accuracy of gas pumps? There is an entity that checks their accuracy from time to time and they are rarily exact. They are certainly close (usually), but not right on. They sometimes publish these in our local paper.
I am the farthest thing from an expert on this - these are just my thoughts.

It *is* annoying. I timed it a couple minutes ago - 23 seconds. I've not seen the Prius boot up - anyone know the time?
