Am I imagining things? Anybody else?

reads Lower or Higher? On my recent trip from SF to LA, CA my GPS consistently read out slower than the Speedometer. When the Speedo read 92 actual speed was 90 on the money and governor was cutting in. the error seemed to remain constant from 60 on up to top speed, meaning the speedometer was 2 MPH faster than actual throughout the range.
Since I had a lot of time (about 6 hours), I also timed the miles to check the speedometer vs the GPS. Gps was correct. Yah know what I didn't think to check though was the Odometer! wait! the GPS reads 1633 miles and the ODO reads 1685. Now, don't think there is an error because of this, the car had over 48 miles on it when I installed the GPS, and it easily could have been 52 by the time I actually finished testing the head unit and fully connected the GOS antenna.
I think they are both so close, it shouldn't be a concern like it was with Honda. My CRV and Pilot were both wildly optimistic, just like their gas mileage estimates.
