ALK Technologies has announced that its CoPilot Live satellite navigation system has now been approved for sale via the iPhone App Store and is now available in UK for Apple iPhone 3G and 3Gs for a one-off payment of £25.99 for UK/Ireland or £59.99 for European maps.

CoPilot Live brings full featured turn-by-turn navigation to iPhones, complete with automatic route calculation by post-code or street, 3D map displays in portrait or landscape mode and turn-by-turn voice directions.

Features include lane assistance, "realistic" signpost displays, speed limit alerts and CoPilot's "ClearTurn" for a more realistic display of junctions.

In addition, there's "Live" services such as a 5-day weather forecast and a location-sharing feature called CoPilot LiveLink that allows users to check the location of friends on-screen or online.

CoPilot says real-time traffic information will also be available later in 2009 as an option.
