You asked essentially the same question here 
How do I rotate the map marker (draw a line on the map at an angle)? and got a workable solution.
The contol does not provide that option however, the final posts describe how to rotate the marker. The advice doesn't suggest rotating the map although that could be done too. See Tim's post.. Direction to point the custom marker must be provided by your external hardware and you must use that information to orient the marker. Tim even provides an aia. Just plug in the 'direction' into his simple algorithm. I think you need to re-read the last posts again. Did you try his example?
To determine the direction using Blocks, if not provided by you external hardware, you need to note the actual location now and calculate a bearing from the previous location.
