Navigation:
So the 705 mapping is useful. It is just that some folks have other tools. I just checked my BB Curve. It needs an external Bluetooth linked GPS machine to have navigation. Of course in some cities, like Denver, much of the biking is on designated first class "trails", more like one lane of a highway.

But the comment that the 705 seems to be biased towards indirect routes raises the question of how useful it would be in a car in a strange city.

Mount and Moving from Bike to Bike:
I've read that the mount is a weak spot. But, y'all seem to think it is OK, if not first class. I don't mind a bit of hassle moving the unit from one bike to another. But, I sure don't want to lose the thing when I'm running from the attacking dog on a farm road somewhere.

Readibility:
Y'all seem to like the larger, more readable screen of the 705.

End?
So, if a person can put the navigation function to use it seems the consensus is that the 705 is the way to go.

Good summary?
