 The NAV is not user friendly. When you enter the car, the media plays whatever it wants to even if your apps aren't open.  The display changes from whatever setting you've selected to show that you're making a call and to whom you're calling; so if you had it set on the speed you have to change it back after starting or ending the call. As soon as the a/c was out of warranty the compressor went out.  I have had it replaced less than a week and it's gone out again.  Besides the fact that my TDI has no value because of the lies the company told, the car is a piece of crap.
