Google has just thrown somewhat of a spanner in the works for satnav hardware and software companies as it has revealed it is to offer free turn-by-turn navigation functionality to its Maps product that will be offered in Android 2.0 devices.

"Maps Navigation" will debut in beta by default on all Android 2.0 devices and appears to offer a comprehensive satnav service that integrates Google's two very popular products, satellite and Street View, which could be used for the likes of lane guidance.

Hit play on the video above from Engadget that sees a Google product manager giving an overview of the potentially disruptive new service and we'll bring you more on this breaking news as we have it.
