One of the most common item to cause a battery drain is the AC compressor control relay sticking on or a CD or coins stuck in the player. I would remove the control relay to see if that helps. Please check out this guide can well.

Here is the location of the relay so you can do the first step. After that remove the radio/CD player. Check out the images (below). Let us know how it goes
