G6 battery drain

I have a 2010 g6 that as had issues with starting. If I leave it sit for over a day or so will have to jump. Quick background, issue started few years ago. Dealer blamed it on battery, so have had a couple new batteries. Also replaced all battery cables, connectors, ground. Problem still persisted so I took to electrical specialist who charged me 300 dollars and said that it could be the body control module, but couldn’t promise. Anyhow I brought to dealer and replaced the body control module. Issue stil persist. So now I have been trying to find the drain myself with multimeter. I disconnected the negative cable, removed fuse for interior lights so it wouldn’t affect it. So the initial reading was about 2.4 amps. After I removed fuse for OnStar it went down slightly. Then I finally got to radio fuse which dropped it to about 0.78 amps. Went to trunk fuse box and disconnected some fuse that said it was for a dvd changer and now reads 0.47 amps. No changes with any other fuses. According to what I read this is still to much draw. Does this mean I may have a bad radio? Any suggestions on what to do next would be appreciated.

Connected meter inline on negative side opened doors closed the latches to shut off dome lights let car sit like that for hour. These were the beginning steps I followed for each time I tested the car. I just followed steps in the video. After finding the fuse by measuring across pins and pulling it I can hook up inline and have less than 20 miliamps. The car can sit for days and start up now and that's alot better.

Can you tell me what video you are referring to? And do you remember which fuse gave you the issue? Thank you
