Unmarked white box with blue light leds on it inside 2014 model

Anyone know what the white box is inside the equipment compartment? It has blue led lights on it and a small button facing the exterior. If you push the button, the leds that are lit up change.

Okay, I figured out what it is but I still don't know what the button does or what the lights on it mean. It's the Sound system/bluetooth audio module. I haven't been able to find any kind of technical specifications on it online that will explain the light codes to me.
