Determining which audio system your Mini is equipped with is simple: if you see logos saying "Harman / Kardon" anywhere in your vehicle, you have the audio system type "Harman Kardon / Top Hi-Fi." Otherwise, you have Base / Standard audio system. That's it!
This is the "Premium" audio system option. If you selected an audio upgrade at the time of purchase, or have "Harman / Kardon" logos in your interior, then select this audio system type.
This is the "Standard" equipment audio system for most Mini vehicles. Not sure which system you have? If you don't have logos saying "Harman / Kardon" in your interior, then you have this audio system.
