I've searched here and called Tesla but so far I don't have a solution. I created a Slacker account on their website last weekend. Not premium, just a basic account at the moment. Since then I've tried all week to login on the Streaming tab to my Slacker account in the Model S but after I enter my email & password, it very quickly displays "Unable to login. Please try again later." Seems like it's not even enough delay to have tried to authenticate over the network - it's nearly immediately failing. That suggests to me some setting or something. I see (from 2013 posts) where there used to be a logout in the Settings -> Apps but the interface has long since changed - I don't see any logout type option anywhere. Anyone have suggestions on this? On the Slacker website I can login, logout, login, see some stations that I set up and customized.
