Hi there! I'm trying to change the wallpaper in my 2013 Mustang GT and no matter what I try, it's not working. I'm prompted for a CD/DVD with jpegs no larger than 1.5 mb on it. So, I burned some images to a couple of CDs and no matter what I do, when I insert the CD, I get the message "Bad file or unsupported format". What am I doing wrong? The CDs have the images on them, the images are there when I look at them on the computer. Is there any other way to change/add wallpapers? Are we unable to add via USB? Is there something special I need to be doing to these CDs when I burn them? Thank you!!!
It sounds like you burned the optical disc using UDF format. The disc needs to be ISO 9660 format with all naming and directory restrictions in force.
If you burned in ISO 9660 but relieved the restriction on directory depth or file naming conventions it won't work.
