Hey guys, I’ve tried the hard reset hitting the menu and phone but nothing happens. I’m about to unplug the battery. I’ve read some of you say to have a radio code available. Does anyone know what the code is for a 2006 XK8? And where do I get that code? I just pulled the disco out of the navigation changer and my disco is the “Navigation System disco for USA and Canada “ there is numbers written on it with a sharpie ( 5536156) don’t know what that means. If I unplug the battery And don’t have a code what does that mean? Will I be locked out of my radio?

I can definitely see something light up on the screen, it just doesn’t display the clock.

Unplugged the battery and it fixed the issue! Awesome!
