The Garmin Nuvi 700 series was launched at the top of the Garmin line to make steps forward in both design and functionality. The Nuvi 750/760/770 units are a change vs. the Nuvi 650/660/670 units with a thin design losing the flip up patch antenna of the Nuvi 600 series, and adding some functionality that is nicely useful. The Nuvi 750/760/770 is a widescreen unit with a bright screen, not marginally bright, but plenty bright for sunny days. The 760/770 series also comes with a TMC traffic receiver that is integrated into the 12V plug. It has maps of North America pre-loaded.
