hmm...i think i had a bad ground connection?? (circuit city for you), i just got it back up for now. i will give it a day to see if the bitch cuts off again. i was suprised because its been working since september and decides to crap out as of a few weeks ago.
b.t.w....i have the terk xm3 antenna, pioneer xm reciever box, and a pioneer p6400 deck
