Use our custom built plug and play wiring harness to convert from a 2018 Golf/GTI S base stereo, Composition Touch or Composition Color to a Discover Pro/MIB2 brain unit and display.

This wiring harness relocates the main quadralock harness in your radio opening to the glovebox, where one can mount a Discover Pro or MIB2 brain unit. 

A Sirius Antenna, GPS Antenna and/or USB extension cable may also needed to complete your Discover Pro/MIB2 retrofit.

Note: Harness has built in RVC/microphone support. When using this harness, your factory microphone and factory RVC will continue to function with your new MIB2 unit.

Note: Depending on your installation, additional wiring/antennas may be needed.
