I got the strangest message last week. I alternate between different screens and do not use the media screen all the time but usually have Slacker playing in the background. I noticed that nothing was playing so I pressed the media screen and got a message that actually said someone else was using my slacker account and that I could change it back by simply selecting something. I do not have a personal Slacker account on my MS, just the factory provided service. It did work and change to my selection but I thought this was pretty unsettling. I do have the latest 5.9 update. Has anyone else else experienced this? I have about 15k miles and this is the only time I've ever seen this.
