Title: Look at other Topo map products before buying this one
Review: Having topo maps on the GPS screen while hiking is something which, now that I've had it, I'll never go without. However this is not the map product I would buy today.Consider instead Garmin's 24k maps, rather than this set of 100k maps. The resolution in the newer (24k) maps is better, more like what you get with USGS 7.5' quad maps/NG Topo/DeLorme Topo.Note that Garmin products purchased for one GPS unit can NOT be transferred to a new/replacement unit (except by Garmin via warranty replacement). Garmin's anti-piracy "unlock" procedure is archaic and tedious. If you ever upgrade your Garmin, you must buy your maps again. One "unlock code" is assigned to one USB-connected GPS device, by serial number, and cannot be changed.If you're looking for the GPS that works with National Geographic's Topo! maps, that's a Magellan.
