That's a product they sell. It looks like an audio cassette with an aux cord coming out of it. I used one for years in my old grand Marquis.

That just wires the speaker output of the device to a set of coils sitting right in front of the tape playback head. GP did an end run around that by wiring straight into the trace in between the head pre-amp and the main amp.
