Stereo does not read Sansa Clip after firmware upgrade

  1. Check your USB settings. It should probably be in MSC mode for your stereo to read it as a flash drive.

  2. You don’t have to revert back to the previous firmware in order to get your volume back. There are about a gazillion posts about that subject here. You just need to change your region in Settings away from Europe. Reset Factory Settings to re-select the region.
