Battery drains overnight

[richjol]

My 2014 Silverado battery was dead after sitting overnight.  I recharged it and it discharged again.  Had battery tested at Advanced Auto Parts and they said it was weak so I replaced it.  Same problem. 

I noticed that with the doors closed, key out, the radio screen is "glowing gray" and does not go out even after sitting for an hour.  If you get in the truck, still no key in the ignition, the welcome screen comes on and the radio starts playing.

The headlights and interior lights go off after about 30 secs.

I am getting a draw of about 200ma that does not decrease.

What should I check next?

Call the dealer and see if there is an update for the BCM or the mylink.

Yes you need update. Myradio turns of even if the key is on acc. Position and engine of if it is cold out or it sees battery low. So yours is way off.
