I found the same thing with my replacement stereo.  I think mine was
about .4 amps.  It's meant to be wired into a circuit that is only on
when the key is on, but of course us campers will want to have the
stereo when we are camped.  My solution was to add another switch in
the pod on the right.  I think I used a rear defrost switch I had on
hand.  That is the power on for the stereo now.
