Grease a 9x13 inch baking dish. Place milk, sugar, vanilla, salt, syrup, cinnamon, nutmeg, and eggs in a large bowl and beat with a hand mixer until smooth. Add bread cubes and stir with a spoon until coated. Pour bread mixture into pan. Cover and refrigerate up to 24 hours.
Heat oven to 400F. Top bread mixture evenly with cream cheese, blueberries and pecans. Bake uncovered 20-25 minutes or until golden brown. Cut into servings. Dust with powdered sugar and serve with maple syrup.
