you can just use the app radio app and click on settings-wallpaper.

No we can't, that just changes the app menu wallpaper, thread is about changing the main home screen wallpaper

Has anyone figured out how to add a custom background wallpaper on a AppRadio3 with an iPhone4/4s? I've created the wallpaper image, gone into the AppRadio app and "added" a "Background.png" file, but there's no apparent way to "open" the file which is what the instructions I read said to do. Seems very weird that it works for AR2 but not AR3? Something to do with firmware maybe?
