I have just acquired an Aera 500 and it is a fabulous bit of kit. Aviation & automotive modes, full-featured (all the usual navigation bits plus traffic & terrain) on a touch-screen the same size as a Garmin 530; bluetooth phone connection, audiobooks, music, photo / video viewer......
Includes both car & yoke mounts and power connections, as well as free database updates for both car & aviation modes.
Brilliant!
