Yeah, it turns off fine. If I try to reboot it via Hijack, I'll get a big screen with the linux penguin that says "Hard drive not found. Consult technical support." Same thing if I just pull out the Rio and push it back in.

However, if I actually turn the car off and turn it back on, it boots up fine. I've seen one post where someone had a similar prob, but it didn't really go anywhere...
