good find. i have a 2013 express with uconnect 3.0. i have a USB in my center console that does nothing with my Galaxy but with my sons iphone it plays songs through the stereo using my radio knobs. i tried connecting a flash drive in that port but it does nothing. will the USB under the dash act any differently if i have it? i'm considering getting an iphone next just to listen to music. i drive 100 miles a day and my truck has no CD player and i don't want Sirius and the regular radio sucks.
