The new Lowrance iWay 600c is one bad mamma jamma of a GPS device. Yeah, it offers all the navigation basics, such as turn-by-turn, text- and voice-guided directions and points of interest, but it can also overlay satellite imagery onto the maps. Plus, it has a large, 5-inch, 640x480-pixel resolution touch screen; a 30GB internal hard drive; marine mode; and an MP3 player. Rad, huh? Well wait, here's some bad news. The satellite imagery is available only in select U.S. and Canadian metropolitan cities, so if you live in say, Beaconsfield, Iowa, chances are you won't be able to take advantage of this feature. Also, 25GB of that 30GB memory is reserved for mapping and satellite images. And if you're still interested at this point, it'll cost you a pricey $800. The Lowrance iWay 600c is expected to ship December 1.
