One of the best perks of having an Android phone is Google Maps and free turn by turn navigation for Android. A part of Google Maps that we often forget about is the Labs section. In Google's own words "Labs is a testing ground for experimental features that aren't quite ready for primetime. They may change, break or disappear at any time." They are also pretty darn cool, offering things like a map scale bar to estimate distance, or a measuring tool to actually measure it, and of course the pre-caching of an area we've talked about before.
Enabling any of these is easy. Open the Maps application on your phone, hit the menu button, then tap "More." Choose "Labs" from the top of the list. Tap on any of the Labs features to toggle it on and off.
