Summary: I bought this Garmin GPS for use on a motorcycle. Considering the high cost of motorcycle-specific GPS units, this is a great alternative that does the job for minimal expense. It's waterproof rated and has the same familiar Garmin navigation interface.
Summary: It's small and compact which makes it great for hiking, however seems overpriced for it's size and minimal features. I guess your paying for the waterproof feature and topo maps. Unfortunately, the topo maps that come with this unit are poor.
Summary: A must for every off roader - don't be concerned about getting lost ever again. There doesn't appear to be the smallest trail out there that this GPS topo can't find. It is taking some extra effort in learning the ins and outs, not as easy as I had thought but slowly it is making sense.
Summary: This is the first GPS I have purchased. I bought it for the Topo/Street map combo. I have a jeep and love the off-road adventures, I figured it would be the best of both worlds and I was right. I don't need a state of the art GPS for off road and street use.
Summary: I originally wanted to pick up the Zumo for my motorcycle primarily, but couldn't justify the cost. What I really wanted was for it to be waterproof and have topographical maps. This one does both of those things and costs way less(I think I paid around $239 in 10/09).
Summary: I received this unit in mid-May. The protective rubber cover for the power cord connector got lost 3 days later. The only use was from testing the unit driving to work and back. Garmin promised to send me a replacement but it has yet to arrive after a month.
Summary: We bought this specifically for a trip to Hawaii, where we'd be driving around the island, hiking on foot, geocaching, and off-road driving. I got this unit in particular as it has the hiking trail maps (they were dropped for the 550 which, otherwise, seems to be the same unit).
