I'm not very technically educated so please give me a break if I'm not making much sense. I have a 2010 Toyota Tacoma with an aux plug-in thing built in. I went to radio shack and bought a 3ft aux adapter that connects to where the headphones plug into a device. When i plug it into my phone and into the aux plug-in in my truck and turn the volume up on my phone, no music comes out of my speakers. I am on the correct station that is needed and i also turned my speaker volume up but no sounds comes out. Am i dumb or something because this isn't working.
