ALK is one of the longest-running players in the sat-nav app business. CoPilot Live dates back to before the sat-nav became a separate device. CoPilot Live Premium is the second incarnation of CoPilot since it crossed over from Windows Mobile with version 8 to the current leading smartphone platforms, Apple's iPhone and Google's Android. It's a major overhaul, both in its interface and underlying functions. This week we took a look at the iPhone incarnation, although the Android version arrived first and there's an iPad build too, for those who fancy a 10.1in sat-nav screen.
