This is a bluetooth receiver made by Metra for their Install Bay line. This is a universale bluetooth device that will stream your music to your system. I use this device often when installing amplifiers into vehicles that do not have a headunit; like a classic car, boat, or a motorcycle. This allows you to plug directly into the amplifier to feed it bluetooth audio signal.
