Matt - the fact that you don't have any green dots in the square box in the upper right corner is a clear indicator that you are not receiving GPS signals on the nav drive, which is why you aren't able to get navigational directions from the system.
First thing I would check is that the antenna is properly connected on the back of the nav drive. There are 4 bolts holding it into the rack. Remove them and carefully slide the unit out. There should be 2 plastic connectors and one small round metal connector going into the back of the drive. The small round metal one is the GPS antenna connector.
If that is connected properly then you may have a bad GPS antenna, which is located up in the rear spoiler.
