I've noticed some weird behavior with my iPod over the past few months that I've had my R56. I use an old 30GB iPod Photo because my iPhone won't charge in my car. I usually just leave the iPod connected in the car, since I use my iPhone for music outside the car. When I turn off my car, I click the volume knob to turn off the music. When I disconnect the iPod from the cable to carry inside with me, it will stay on the "home" screen until the battery dies - it never goes to sleep. I can get it to behave normally and eventually go to sleep mode by switching the hold switch back and forth. I have recently discovered that this also happens if I leave the iPod in the car, plugged in - the battery will eventually die over the course of several days, because it's on all day while I'm at work, and all night after I get home. Has anyone else noticed this behavior?
