JaapJan,

Does the car USB operate an audio output? In my car I'm fairly sure it's just a power socket, but haven't checked.

What car is it (you're going to say Bugatti Veyron, aren't you... sick)?

Sooloos, Roon, G series (with LPS upgrade), 800 series (with LPS upgrade), HD621, AC200, Prime and PS, DSPs old and new.

Purdeys, Moke, Leica, 'Blad. Only the best.
