I have the same problem when battery is going bad like it does every year, the first thing I do is pull the fuse so monsoon doesn't count all six CDs every time I start up. I have to admit I love not having the extremely loud, battery draining, and annoying door chime and would like to disconnect that without disabling radio.
I don't know if best buy is still open amid the CV panic, but those audio guys can tell you exactly what you need and then if you don't like the price you can buy it online elsewhere.
I have a good experience with most junkyard parts except the audio stuff.
