System Software Missing


   I have a Garmin 2589lmt.  I had issues with the unit displaying: System Software Missing 

   I went ahead and uninstalled the Garmin Express from my Laptop ( Win 8.1 OS ). Restarted the Laptop and went to and Downloaded the latest Express Version for Windows. Followed the prompts to install Express, Conected the Unit and did the Software update; I still get the same error.

   The GPS is out of warranty.

   Any thoughts are appreciated.

Thank you.
