currentBearing

Current bearing in degrees. Current bearing in degrees, measured clockwise from true north. Typical values are 0 to 360 or NaN, negative values will be subtracted from 360 (e.g. -15 => 345), values greater than 360 will be have 360 subtracted from them (e.g. 385 => 25). For this property to be used the bearing tolerance also has to be set.
