Hi guys looking for some help here I recently purchased a new cord that goes from the iPod integration system into the glove box because the old one broke. it looks like it's the old wide 30 pin connector cord for the old iPods I bought a new adapter that will connect to that 30 pin and turn into a aux jack at the other end I attached it to my samsung galaxy s5 to try to play Pandora and had no luck I'm looking for any help here please the dealer has no idea what to do, i know how to get to the aux option but it plays no music
