I have Slacker up and running again. Here is what I believe has happened. Favorites were being stored from when I first received my car. They were just not displayed (display window was blank). I could touch the blank display window and a favorite would appear so they were “there”, I just could not see them. My DS told me to reboot the center display. When I did, Slacker ceased to function. My favorites did appear. I purchased a premium Slacker subscription and now it is working again. This is what I sent Tesla- I believe the center screen reset caused a push of the Slacker username and password. The subscription on the pushed u/p had expired and thus Slacker would not slack.... The car is three weeks old now and it is my understanding from the forums that there is a 3 month subscription included with the car. It is not worth your or my time to go back to the included subscription for a total of $18 so I am good to go. However, you can prevent these problems in the future by warning customers that reboots will push new u/p and the new ones may be expired. You could simply document the provided subscription details for each car and the owner could re-enter the details after a reboot as well. Either way, a heads up will prevent an action ticket on your end.
