How to check if Rockbox has been properly installed?

Rockbox has its own GUI that’s pretty horrible. You need to look at their “Themes” page and download soome that might be nore suitable to your needs/wants/desires, etc.

Bottom line . . . if you installed Rockbox correctly, you would definitely know it. Have you read any of the Rockbox manual so you’re familar with what it looks like, or what to expect?
