Touch Screen Blank/Delayed Boot

[FlyPacNW]

Cranked up the truck this morning and found the Intellilink touchscreen did not boot up. After a few minutes it did come up but only to a “maintenance page” with a prompt that says “Waiting for Update Media”. To me this sounds like a firmware update is pending but I didn’t do anything to prompt this. 

 

Any ideas how to get the screen back or am I due for forced update from GMC?

 

thanks

Exact same thing happened to mine. Had to replace the HMI cable/module.

 

This might be helpful.
