Hi I have just bought a 2012 twinair Fiat 500 and today it started talking to me . I missed most of the message as I thought it was the radio, but it said something like......'something? auxilliary is nearly empty you will need to ? ? usb to restore it'.It hasn't repeated the message.Should I panic?Thanks for any help.Ps Sorry if this is not the right place for this type of message.
