You may have noticed that Google Maps for Android has been updated in the last day or so. Normally these updates do not add anything too exciting. This update however has added a couple of features that make this an essential app for travelling around. First of all they have introduced Public Transport directions, this will tell you which bus to catch, where to catch it, what time the next bus is coming and where to get off. The second interesting thing they have introduced is, the ability to download a section of the map to use when you do not have a signal or you are roaming abroad. This is available in the labs section of the app. Below are a fe screenshots so you can get an idea of how these features work.
