A versatile travel assistant, the Garmin Nuvi 300 comes with detailed maps, automatic routing, turn-by-turn voice directions, and touchscreen control. This portable GPS navigator is small in size; it could be compared to a size of a deck of playing cards. The Garmin Nuvi 300 also includes an MP3 player, audio book player from Audible.com, JPEG picture viewer, world travel clock with time zones, currency converter, measurement converter, and calculator.
