Rare options in pictures

[GERMANIKS]

So top hifi is logic 7 ?

Yeah, on late e6x you also had a 4th sound system introduced, called individual audio, providing over 700 watts of power, better speakers, surround system equivalent to Logic7 it is supposed to be significantly better than the Harman Kardon Top HIFI Logic7.
But an Individual Audio amplifier is a very rare option on late e60, like the CIC, if you find one, it will be expensive.
