Anyone else have these problems? When I try to use my Apple USB cord to my phone, it keeps popping up a message "Trust this computer" and dissapears before I can hit trust, it will just keep popping up & go away. And when I use my AUX cord, It would randomly disconnect & i'd have to pull the cord out of the AUX port and plug it back in. I have an iPhone 5C if that matters at all. Thanks.
