Let's not kid ourselves, navigation devices are the latest technological threat to our health and well being in the US, making them guest of honor #1 at the Engadget HQ. This particular people killer, the Maestro Elite 4350 from Magellan, includes a number of life-endangering features, like 3D landmarks, text-to-speech, voice commands, Life Traffic info and -- worst of all -- built-in AAA travel info. It's a veritable death trap. There's also historical traffic info, which lets you know how fast a certain road averages for certain times of the week, which sounds pretty neat. There's a 4.3-inch screen, SD card slot, Bluetooth and an FM transmitter. No word on price, but don't expect cheap.
