The Crutchfield harness part is Nr 120701784, and antenna adapter is Crutchfield Nr 1040VW12.
This allows an aftermarket XM or Sirius radio to be installed as a direct plug-in to the 996.
Depending on the model year, you might also need a OEM-2 Amp interface.
So, lets see how this works.
If anyone tries this before me, please post your results.
