iDatalink plus VW
iDatalink's HRN-RR-VW1 interface harness allows you to connect a new car stereo in select 2002-16 Volkswagen vehicles, working in conjunction with iDatalink's Maestro ADS-MRR or ADS-MRR2 module. Once connected, you'll retain the use of your steering wheel audio controls, navigation outputs, and amplifier turn-on in these vehicles. You'll also gain the ability to assign secondary functions to your steering wheel audio controls.
The package includes connectors that plug in between the Maestro module, your Volkswagen's radio's wiring plugs, and your new car stereo. You'll have to solder or splice together this harness's power/ground, illumination, speaker, and navigation output wires to the corresponding wires on your aftermarket receiver's wiring harness.
Extra functionality with an iDatalink-ready receiver
With an iDatalink-ready car stereo , you'll retain the use of your digital fader with your VW amplified system, along with factory Bluetooth® connectivity. You'll also be able to set up gauges on your receiver's screen to monitor engine performance, tire pressure, and other functions. You can even send navigation information from your new receiver to the multi-function display in your VW's instrument cluster.
Installation note: The HRN-RR-VW1 harness must be used with the iDatalink Maestro ADS-MRR or ADS-MRR2 module to connect a new car stereo to your Volkswagen vehicle.

This works with a 2013 Jetta Sportwagen, but idatalink's website doesn't list the wagon separately from the sedan, so Crutchfield doesn't list it as fitting. The Crutchfield advisor didn't know, so I called the manufacturer to confirm. Installed and works great.
