You don’t have to live in Colorado to use Garmin’s new handheld GPS . The Colorado 300 is a handheld unit with a color display and lots of extra travel-friendly features like an MP3 player and book reader. Garmin announced new products at CES including the Garmin nuvi 260 and the Garmin nuvi 850 but last years models like the Garmin nuvi 360 or the Mio C520 can offer some very good values at prices under $300.
