Since I have the special equipment Family, the MDI interface and the AUX is located (jack) input of the vehicle in the box beneath the center armrest. I have the car since mid-September and was looking for an external hard drive that fits in there reasonable. Should anyone have a similar problem: I have for the Toshiba STOR.E Basics External 500GB Toshiba STOR.E Basics 500GB hard drive (6,35cm (2.5 "), USB 3.0) decided since it has good cut in test reports and (which is very important) fits the dimensions in said box.
Both in combination fully meets my expectations, to have a part of my music collection in the car having to store without a bunch of backup CDs in the car.
I can only recommend the cable, the original cable from the manufacturer is the added good value to any reason, even if it's just 4.00 are (Škoda price is 20.90 for the original cable).
