I love my 60 and love the sunroof. However, I am getting a whistling from the left side of the sunroof and was wondering if anyone else has experienced this Chinese torture over 55 miles an hour? Also, if anyone downloaed the latest software from California, be aware that your navigation screen may have been altered. Since no one knew in advance how to correct this issue, the bottom line is to continously (sp) enlarge the map screen with your fingers until you zero in on your specific location. Before I was seeing the Arctic circle to Jacksonville, Florida.
