For coordinating tracks, you can either edit your tracks to have a common start time in MapSource or you can export into xml or txt and do the same. Once that is done, you can import into MotionBased... you may have to convert it through G7toWin as the MotionBased import is not too forgiving. Just remember that MotionBased needs an Active Log, not a saved track. Saved tracks loose some of the timestamp data that is needed to drive MotionBased graphing.
