MY SF Sport has the premium sound/navigation system installed.. the past few days when you start the car, the radio screen shows the "Blu-Link" loading screen.. the progress bar goes to 50% then 100%.. screen goes blank for a second and the same thing repeats itself over and over for about 15 minutes..and you cannot display anything else..finally it loads, normal radio or xm radio screen returns and everything works fine for the rest of the day but the next day the same thing happens.. I do not subscribe to Blu Link.. any ideas?? If I take it to dealer which is over 25 miles away, it works fine by the time I get there.. ?????
