Customer Review: Poor quality - avoid
I bought the Garmin GPSMap 60CSx and about $400.00 worth of software. I was under the impression that the TOPO US 2008 product was the digital equivalent of the USGS 24K - but due to space concerns I assumed it would be perhaps half the resolution (otherwise my GPS would be the size and weight of a car battery). I was greatly mistaken at how inaccurate it was. After reading many other reviews, I said heck with it and ignored the nay sayers in favor of purchasing it. In my opinion, this item is worthless. I recommend that others avoid it. Garmin’s units are great, but their maps and licensing (especially the unlock wizards) are a joke. I recommend buying another product altogether - the nay sayers are correct.
