I own the 60Cx, which takes the much larger micro SD cards and had a few other good features. i like it a lot, use it for both driving and hiking. The auto navigation feature isn't that great, but it is very handy in the city if you want to locate something or just figure out where you are (which I never need to know, I always know where I am). The screen is great and the accuracy is really good, even on steep slopes in narrow valleys under lots of trees.
The garmin map software is not great, though the street maps are handy to have. I wouldn’t buy the outdoor mapping software, just carry a good map (which you should anyhow). I didn’t get the baro altimeter or mag compass feature, since I carry a separate compass anyhow and you have to know your local altimeter setting before you can use the baro and it’s hard to pick up ATIS w/o a radio J
I recommend it. Bought mine of Ebay for about $375.
