Recently, the folks over at xda-developers.com had figured out a way to make Google Maps Navigation Beta to work on a T-Mobile G1 by hacking into it. This time Google has officially announced that those who are using Android 1.6 or higher will be able to use Google Navigation Maps.
As you already know, Google Maps Navigation is an internet-connected GPS system with voice guidance and automatic rerouting, that runs off your mobile phone. On this update you'll find the new Layers feature, which lets you overlay geographical information on the map. You can also view My Maps, Transit lines, Wikipedia articles about places, and more.
Google wants you to have a happy Thanksgiving, so if you are traveling, you'll be able to enjoy the benefits of Google Maps Navigation in your car. Is still missing some 2.0 features, and it still works only in the US, but many will be happy to have this helpful feature on their Android phones. Enjoy!
