Android Wear device users should expect a minor although expected over the air software update. The 4.4W1 update coming to the Moto 360, LG G Watch and Samsung Gear Live brings a range of features and functionality. What we know of so far are the latest version of Google Maps with alternate destinations, built-in controls for multiple repeating alarms. This isn't yet the bigger expected update to Android Wear which Google says will enable users to, ".... listen to music stored on your watch via Bluetooth headphones. And if your watch includes a GPS sensor, you can track your distance and speed too."
