Navigation system frozen

Asked by Jun 29, 2017 at 12:29 PM about the 2011 Lincoln Navigator RWD

Question type: Maintenance & Repair

After accidentally installing the map update
disc before the software update disc, the
entire system froze. Unable to use
Bluetooth, radio, CD player..nothing. Tried
disconnecting the battery (twice) and the
system is still frozen. It keeps asking for
"disc 2" but when I put in another disc it
says it's an invalid disc. How do I reset the
system or delete what I installed?

The program get got corrupted when you did it wrong, so now the unit will have to be removed and sent out for repair unless your dealer has the equipment to do it. Another thing is do not disconnect the battery without using the saver tool that plugs into the OBD2 port, disconnecting the battery can and does cause BCM units too crash making all the accessories inoperable and that can only be corrected at a Lincoln dealer.
