[Android Auto General] corgin:
Oh, yeah I tried different phrases beforehand (sdcard, storage, card, etc.), Sdcard was the original path that worked before haha. So I tried the commands and I see /data/knox/sdcard (or tmp_sdcard) below. I'm assuming that some sort of recent security patch with knox might be preventing me from actually loading the sdcard? My sdcard is 128GB but the /media_rw path doesn't seem right either. Hmm...
