Is there a way to force updates? The PHL TAC does not show up in the list of available updates and on my 720, the airspace is very incorrect. There have been major changes to the PHL Class B recently that are not reflected on the 720. Thanks
I once got a corrupted KC sectional that cuased the scrolling map to freeze. I was able to delete it, then the update service re-downloaded it and everything has been fine since. I'd try deleting the out-of-date TAC, then trying the update again.
