Poly-Planar Auxiliary Port

Does your present stereo lack a docking station for an iPod, smartphone or MP3 player? Don't despair: Many sets have an "aux" or auxiliary port in the back that allows you to plug in an audio jack such as Poly-Planar's IC3.5PM panel-mounted port ($15, polyplanar.com). This allows you to plug in and play most portable audio devices using your stereo's aux input.
