First, you need to setup your account for your Sony Bravia Internet Video Link device or TV.
Please go to http://internet.sony.tv and follow the directions to setting up your Sony account.
Once you have your Sony account setup, and you are logged into the Sony website, please click on the “Personalized Music and Video Services” link on the Main Page.
Then click on “Link to Service” under the option for “Slacker”. It will then change to say “Unlink From Service” under the “Slacker” option once you have successfully linked your Slacker account.
