Our take on the iDatalink HRN-RR-VW1 Interface Harness

by Bob Bihlmayer

iDatalink plus VW

iDatalink's HRN-RR-VW1 interface harness allows you to connect a new car stereo in select 2009-up Volkswagen vehicles, working in conjunction with iDatalink's Maestro ADS-MRR 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 select radios from Kenwood, Alpine, and Pioneer (see Details for specific models), you'll retain the use of your digital fader with your VW amplified system, along with factory Bluetooth® connectivity. With select Kenwood and Alpine receivers, you'll also be able to set up gauges on your receiver's screen to monitor engine performance, tire pressure, and other functions. With 2014 Kenwood navigation receivers, 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 module to connect a new car stereo to your Volkswagen vehicle.

Highlights:

  • works with Maestro ADS-MRR module to allow installation of new receiver in select Volkswagen vehicles
  • retains the use of your steering wheel audio controls and navigation outputs in select vehicles
  • retain Bluetooth with select Kenwood, Alpine, and Pioneer touchscreen receivers
  • warranty: 1 year
  • Our 60-day money-back guarantee

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so, then check here for a list of parts. You can also call an Advisor for more information.

vm replacement radio harness for idatalink

Written By Me2, BFE, OR on Friday, August 15, 2014
Crutchfield Customer Review (What's this?)
 
This is just a radio harness but makes installs pretty much plug and play if using the idatalink RR controller box.
Pros:
much easer install process
Cons:
requires yet another purchase of another product to add to the cost of the radio swap.
