Spoke to support and they sent the following email instructions. I followed the steps (replace the file on your device if challenged) and it rebooted fine and completed the Touch Screen Update
******************
Plug device into computer
Open device as a drive
Open the Garmin Folder
Remote Sw Folder
Unzip the 006B255000.gcd folder attached and drop the .gcd file into the remotesw folder
Disconnect the Edge from the computer and then this should go through a touchscreen update again.

Happy Riding.
