Pondering these two GPS units. I want the small size for other uses for sure, the 76C is pushing the size envelope for me. The Magellan has SD memory slot, this is a big plus so far as the 60CS only has 56MB permanent internal memory. The 60CS does auto routing, but only if you buy a $140 mapping product on top of the unit. I'm not so sure I'll be doing this, I really don't think I need the feature. My main question at this point is with regard to autorouting. I understand it as you pick your destination and the unit will automatically route you with turn by turn directions right? If so, without using autorouting, you can select waypoints at each intersection on the route to get a somewhat similar result can't you? I.e. the unit will beep as you approach each waypoint, each of them marked at each turnoff on the route, mostly giving the same result ...right? At this point I'm leaning towards the Explorist because of the memory expansion capability, though it doesn't have any ability for auto routing from what I can tell in the manual for it. Has anyone had both an autorouting model and a non routing model and just how much is it worth it to have the autorouting as an option? Also, I'm no world traveler. The most I'd need to load at any given point would be a 1k mile route roughly. Anyone have any idea if 56MB is enough to load detail maps for a trip like that?
