Mio C310

Similar to the Mio C710, the Mio C310 offers a more affordable ($500 vs. $650) and basic system for those looking for a GPS device. It lacks some of the advanced features of its sibling, such as traffic services and integrated Bluetooth, but it does come preloaded with maps of the United States, and it gives text- and voice-guided turn-by-turn directions. The ultraportable gadget also has a built-in MP3 player for music and audiobooks, and sports an all-white casing. For more information on the Mio C310, please read our review of the Mio C710.
