I have a 2014 RR. It doesn't happen all the time but sometimes when driving 80 + MPH I get a fairly loud whistle / whine coming from what I think is the dashboard area. It's very hard to isolate because of the frequency and it seams to be speed dependent because if I drop the speed a few MPH, it will stop. Here is a link to a recording of the sound. Thank you
