Here's my dilemma, I have a Toyota 4runner that did not have an Aux input to plug my smartphones in to play music through car stereo, so I yanked dash and radio out and bought a kit to hook up through radio and led the 3.5 mm cable out through glovebox. The problem is this: the cable end is too thick and won't fit through any of the cases I have tried. I need to find an extension with a really thin plug end that I can get to fit into phone with case on. Can anyone suggest one? I have seen many online but can't really tell if they will be thin enough.
