Hello everyone! Last night I attempted to update my navigation OS on my MKIV system. I used a disk that must have had an issue and now I have nothing showing up on my navigation screen and the power light is out on the MKIV computer.

When I put in the disc it briefly said "OS update" something or other and the screen went blank and stayed that way for 20 minutes. With no other recourse I had to turn the car off to find out what to do next.

I have tried to reinstall the OS with a different copy but the car does nothing when the OS disc is inserted, just more blank screen.

I burned the OS disc using IMGBurn and used 1x speed. Open drivers door, trunk, key in position 1, insert disc and wait. Nothing happens.

What can I do to get the nav back to working order? Any help would be appreciated. I have searched the forums and found similar issues but unfortunately no resolutions to the problem.
