The Double Apex Aux Port is a standard stereo input jack that integrates perfectly with your Volkswagen's interior.  The universal connection is compatible with any iPod, MP3 player or other device that has a head phone jack or a 3.5 mm stereo output.  The Aux Port can connect to any aftermarket radio with a stereo input, replace an outdated iPod connection, or replace a hard to reach aux input located in the glove box or armrest.
