Additionally, six orbital planes are used with forty five degree inclines for accuracy and reliability. (Glandon, 2010) With the technical advances, the systems’ basic functionalities and capabilities as stand-alone navigation systems can be said to have reached a substantially high level. And having acquired car entertainment functionalities as well, automotive navigation systems have now begun seeking a new direction to evolve in.
