After redoing the wiring in my passat, my mkII doesn't go to sleep correctly with the 12v perm power (yellow) wire attached to my cars 12v perm power line. Turning off the ignition, or selecting power off from the menu causes the audio to stop, but the visuals keep on going as if the player was still on but not playing anything. After 180 seconds the player powers itself off completly as it should.

Without the 12v perm power line connected the unit powers off and sleeps correctly, it also works fine w/ the AC adapter.

This seems to me like it could be a software problem, but I haven't heard any other reports of this happening. Anybody have any ideas?
