The 2610 is powerful and fast. Recalc can often complete before you get a quarter mile...
One feature I really like about it is the ability to put as many waypoints as you want in there, and have it find an optimum route for you. For instance, put in your final destination, say Key West and let it do the route and get ready to navigate. Then hold the Route button a second till the menu pops up and start adding waypoints, like hotels, whatever. It will auto route them, optimize the route for time or distance, and walk you through it. This is SUPER for touring and sightseeing as well. Put in all the monuments in DC, or the major points of interest in a big city and just let the 2610 guide you around wiht nary a wasted turn.
There's a great undocumented features list at
