so.. got a new Silverado SS not too long ago and installed my Avic-d3. used the GMOS-04 since i have the onstar and upgraded stock system. after a few days of messing around i finally got it installed. But i woke up a few times to a dead batt. After taking it to a couple shops my friend finally unhooked the batt and used a amp meter to see if there was a draw when the truck was off. there was a .79 amp draw. So we started pulling fuses to see where it was coming form. low and behold it was the stereo. So i took it out and installed my stocker for the time being. Why would my Avic be drawing that much??? any help?? 
thanks in advance!!
