// listening
notification = EAAccessoryManager.Notifications.ObserveDidConnect ((sender, args) => {
    /* Access strongly typed args */
    Console.WriteLine ("Notification: {0}", args.Notification);

    Console.WriteLine ("Accessory", args.Accessory);
    Console.WriteLine ("Selected", args.Selected);
});

// To stop listening:
notification.Dispose ();

//
//Method style
//
NSObject notification;
void Callback (object sender, ExternalAccessory.EAAccessoryEventArgs args)
{
    // Access strongly typed args
    Console.WriteLine ("Notification: {0}", args.Notification);

    Console.WriteLine ("Accessory", args.Accessory);
    Console.WriteLine ("Selected", args.Selected);
}

void Setup ()
{
    notification = EAAccessoryManager.Notifications.ObserveDidConnect (Callback);
}

void Teardown ()
{
    notification.Dispose ();
}
