Ok, so with a driver download my Commando can now talk to my pc Here is the ongoing "problem", I have MP3 music files scattered all over the place (from the various downloaders I used), they are all listed in three places, the "master list" which also has my ringtones, the "Music" app that came on the phone, and "Play Music" app that was recommended to be used. I can play music all day on headphones no problem but when I plug the USB into the stereo (Pioneer) in my truck it will only play the "master list" including the ringtones. What have I done wrong ? I've tried to make a playlist as per the phone instructions but the pc keeps telling me that I can't do that. And the partial playlist I made in the "Play Music" app isn't recognised by the stereo either. It IS one made to play MP3 and others through the USB port Any assistance with this is greatly appreciated in advance, the people at the Verizon store are no help at all except to say I "can find it online"
