Yes - I had the same problem with my 8.4 non-nav. Last time I brought my truck in to the dealer they updated the Uconnect and now the USB plays perfectly. Check with your dealer to see if there is an update available.Anyone having issues with usb sticks remembering last track played? My ‘16 1500 always remembered where I left off playing. Strangely enough it always returns to the fourth track off my entire folder structure.
