Hello, I have a droid razr maxx and have been trying to play musin on my car stereo pioneer deh-p4200ub using a data cable due to the fact that i don't have the bluetooth adapter for my head unit yet. everytime i connect to stereo i get "error 19" displayed on head unit. I've tried using mass storage and mtp to reconize sd card in phone. i found that if ihave the music stored on internal memory of phone it will work but i have 14gb of music on sd card that wont fit on internal storage. is there any setting i can change for this to be compatable?
thanks in advance.
thanks in advance.
