I received a message from the DMD team before the weekend stating there was a bug with the mapping screen etc. My two big issues, the blank white screen in maps, the constant need to re-enter the license code which only happened on the map screen (Not Roadbook or others) were both corrected after Build 3.00163.
I updated to the newest version out today Feb 3rd and it all seems to work correctly. Thank you for addressing these issues.
