Although Google has added navigation to their Google Maps service on Android 2.1 and newer builds, one of the downsides of the navigator is that you need to have a data connection active to use it. CoPilot Live is a navigation program that is capable of downloading customized maps of many regions of the world to the storage card. There are millions of points-of-interest and other features to help you get to where you need to go. The full version of CoPilot Live is $29.99 on the Android Market.
