Magellan this morning officially unveiled its first significantly redesigned GPS unit in recent years. As seen at the FCC, the Maestro 4700 is significantly slimmer than most other models even with its larger 4.7-inch touchscreen. It's also Magellan's most advanced with 3D landscapes, Bluetooth calling and predictive traffic alerts that offers to reroute based on usual road congestion patterns.

The company's mapping hardware also has an upgrade in software, with more space for bookmarked locations as well as a new address book, larger fonts that are more readable at driver's seat distances and a parking-friendly mode that remembers a car's location and switches to pedestrian mode. To accommodate the smaller physical size, Magellan uses microSD cards for storage.

The Maestro 4700 should ship for $300 on July 15th.
