The function starts navigate to taken location.

Parameters

lpError	Additional error information returned from Drive.
lpLocation	Reference to instance of SWayPoint class which contains informations about target.
bSearchAddress	Flag determining whether GetHistoryList searches for address or not. true - StartNavigation fills address member of each SHistoryRecord with corresponding address. false - StartNavigation does not search for address.
