Hi, can anyone help with a faulty USB problem in my 370z please? When I have the radio on the AV will suddenly start trying to read the USB memory to which I have an ipod connected. If I switch back to radio, a few seconds later it will repeat until it is doing it constantly. Even if I turn off the AV completely, it will switch itself back on and I get a message saying "reading USB memory". I have had an new USB port fitted but this hasn't resolved the problem. I am 3 days out of warranty and Nissan want to charge me for diagnostics and any resulting work, despite the fault being reported before warranty ended.
thank you in advance.
