Garmin and TomTom units already on shelves everywhere, f-tech's got your solution. The same folks who brought you the (partly) solar-powered Solar 7 GPS unit have toned things down with the NAV 550 Professional Navigator, as it resorts to just the basics when leading folks around. Powered by a 400MHz Samsung RISC microprocessor, the device provides turn-by-turn voice guidance and boasts integrated smart2go maps, a 3.5-inch touchscreen, SiRF Star III antenna, SD slot, stereo speakers, and a (presumably non-explosive) rechargeable Li-ion battery. It also sports a headphone jack and USB 2.0 connectivity, while touting the ability to "operate indoors" by receiving "tracking signals down to -159dBm." Although pricing and availability details have yet to surface, we're fairly certain this ho hum offering won't dent the travel budget too bad when it hits North America.
