Spray your Crock Pot with non-stick cooking spray or use a Crock Pot Liner to keep it clean.   Arrange cinnamon roll pieces on one layer at the bottom of the Crock Pot.   Beat eggs, whipping cream, maple syrup, vanilla and cinnamon until well-blended.  Pour evenly over the first layer of rolls.  Add second layer of rolls over the first.   Drizzle one pack of icing over this layer.  Cover and cook on low for 2½-3 hours until rolls are done, golden and start pulling away from the side of the Crock Pot. Drizzle remaining icing packet over the top of the rolls and serve immediately.
