This may have been listed but i didnt see it anywhere in the FAQ or here. I have a Rio Car 30GB unit I just got a few days ago from SB. On AC power, the unit won't stay powered down when I use the "Power Off" option. It will go off and stay that way for a bit then when I look back over it's powered up and alternating between the "Souce Player" and "Source Auxillery" screens. This is running 2.0 beta 7 with the latest Hijak installed. Anyone got any ideas on this one?
