Nav/Audio display glitch

When I started my car this morning after being parked for a couple of hours the Nav/Audio displayed only the Hyundai splash screen. AM/FM and XM played correctly, but the screen display did not change. USB did not work, and the nav screen did not display when I pressed the map button. I restarted the car several times with no success, then parked again for about 30 minutes. When I then started the car again the display worked correctly. This must be some sort of transient glitch - does anybody know of any related reports or TSB's?

This is a known issue and I think finally a TSB exists for it, typically it's the Amplifier-XM unit going bad. If you simply shut the car off it will not fix the problem, but after the car sits for 10+ minutes everything "corrects" itself. They replaced mine twice in the span of 1.5 years, since the last replacement all has been working well.

You wouldn't by any chance know the TSB number, or have your work ticket? Maybe I could use that to point my dealer in the right direction.
