I have a 2012 Equinox with Nav. It plays MP3 audio files from a USB flash drive fine. When I select Playlists, the playlist names show up with 0 files underneath them. The playlists have a M3U extension and display correctly on my computer. Should these be visible and playable through the car radio?

 

Short answer is yes.

BUT you should look at page 7-31 in your owner's manual as there are some requirements for the playlist:

‐ Applicable playlist extensions
are: .m3u, .pls.

‐ Playlist entries must be in the
form of relative paths.

‐ The system attribute for
folders/files that contain audio
data must not be set.
