The aera 660 aviation portable puts the latest Garmin technology in the palm of your hand, and it carries on our tradition of creating innovative navigators that go way back to the beginning of handheld aviation GPS. While aera 660 is light, compact and fits in any flight bag, it's also packed with capabilities. As a dedicated navigator, it quickly and reliably acquires GPS and GLONASS satellite constellations and combines advanced navigation tools with rich, interactive, dynamically drawn aviation maps. And it displays it all on a bright, sunlight-readable 5-inch diagonal capacitive touchscreen display.
