The 599 has simply the most awful stereo - especially shocking in contrast to the the sublime nature of everything else in, on and about the car. I have decided to replace the unit with something more user friendly. The speakers are perfectly adequate and I'm looking for something simple to operate, with straightforward controls for volume and tone, good reception for FM & AM and the ability to control the current 6 disc CD player. I may as well investigate units with flip up GPS screens and satellite radio. Whatever I get must fit in the current space occupied by the factory unit. I have no desire to drill holes, replace speakers or otherwise attempt to put a recording studio in my car. I would appreciate suggestions from all who have replaced stereo head units in late model Ferraris.
