Hi all, I have a solid tip for all of you new or soon to be owners. I emailed [email protected] and asked them for my Slacker Radio username and password, which they quickly replied and provided back to me within a few hours. With that info, I went to the Slacker website on my Mac and logged in, went to account settings, and changed the low quality audio setting to high! Now I have the higher quality 320kbps streaming audio in my car! Enjoy!
