There were problems with early stereos causing battery drain, basically, the radios were turning themselves on!!
Firstly go into the settings and make sure ignition logic is on, if this was off, then try it overnight, if battery still goes flat, a new recon radio, which has to be reprogrammed, and you need the security pass, will have to be replaced,
Hope this helps,
