If you're in the market for a basic GPS navigation system, Mio Technology's Mio Moov S510 might fit the bill. Priced at just under $200 (as of August 31, 2009), it offers a large, uncluttered screen, voice directions that name streets, and a generous points-of-interest database in a sleek, good-looking package. But the device has some usability issues, and you must forgo (or pay extra for) connected GPS features (such as real-time traffic alerts) that several competitors offer at no extra charge.
