This is a forum section for a 1st-gen GS300, here is a section for SC models.
There were two systems offered in those cars, and more likely than not, you will have a regular Pioneer system. The optional system was made by Nakamichi, the sound is impressive even by today standards, but it is a really rare option. The whole system is different, so if you were to have a Nakamichi unit, there would be a logo on the face of the Head Unit, below is the picture of a said unit.
