Annoying error message about Slacker

I keep getting this error every few minutes. And I get it every time I try to select an audio source. I can't even change the audio source to say AM or FM. How can I make this stop? I don't know what Slacker is but I don't want another on-line radio service.

 

Update. After playing with it I can now select other audio sources. But this damn head unit continues to want me to link a Slacker account which I don't have (or want).

 

There is an app for your phone that needs to be downloaded, then if you have your phone paired to the truck and the entune app running/enabled on your phone, the apps on the head unit will work. Slacker is a free web based audio streaming service

 

Dont download the app, its trash. What you need to do is go into settings and do a factory reset. This will clear out all that crap.

The slacker notification is there because someone linked a phone with the entune app on it and caused it to link.
