Yeah, I learned that too... Either that, or get in the car and drive further down the bay!
The Nav info just reminded me of last weekend... I now use my Garmin eTrex Legend on my mountain bike. I was flipping through the displays and noticed the top speed it's registered (since purchased) was 146 Mph. Wasn't on the bike! Or the Murano. Really had me wondering!!!
Now I think about it, I did loan it to a couple of friends... I wonder if that data's still in there?
Too bad you can't download what the navigation system's seen.
