About the CRUX SWRVW-52 Wiring Interface
Wire in a new radio
You'll only be able to retain your steering wheel audio controls with a compatible car stereo made by Alpine, Blaupunkt, Clarion, JVC, Kenwood, Pioneer, or Sony. No other brands are currently compatible. Check the Details tab to see if steering wheel audio controls are retained in your vehicle.
Wire in a new radio
Crux's SWRVW-52 interface ensures that you can keep the steering wheel audio controls and the factory amplifier (if present) in your Volkswagen when you replace the factory radio. Once you connect this interface to the wires on your new stereo's wiring harness, you've covered the power, ground, and factory speaker connections for your new stereo.
The SWRVW-52 interface also offers the reverse, illumination, and Vehicle Speed Sensor (V.S.S.) outputs that you'll need if you're installing a navigation receiver. The Crux interface is designed to work with the factory Volkswagen CAN-bus systems.
Note: This interface will retain steering wheel audio controls when used with Alpine, Clarion, JVC, Kenwood, Pioneer, or Sony receivers.

Featured review
Operates as advertised. Allows you to keep premium amps from OEM system. You do have to make sure you don't connect unnecessary wires (I.e. Steering wheel control wire if controls are not present and this will cause new head unit to ignore the remote).

Features
Volkswagen Radio Replacement Interface: The CRUX SWRVW-52 is a radio replacement interface for select 2002-up Volkswagen vehicles (w/ CAN bus systems). It facilitates the integration of an aftermarket radio to enable retention of factory features when replacing a factory installed radio in select Volkswagen cars (with or without factory-installed amps). This interface is also pre-programmed for retention of steering wheel controls.
Compatibility: The CRUX SWRVW-52 is supported by the following 2002-up Volkswagen vehicles with CAN bus systems and non-amplified or amplified factory audio systems.
| Make | Model | Year |
| Volkswagen | Beetle | 2012-2013 |
| CC | 2009-2013 | |
| EOS | 2006-2012 | |
| Golf | 2002-2013 | |
| GTI | 2006-2013 | |
| Jetta | 2002-2013 | |
| Passat | 2002-2013 | |
| Rabbit | 2006-2011 | |
| Tiguan | 2009-2013 | |
| Touareg | 2004-2010 |
Steering Wheel Control Retention: The CRUX SWRVW-52 also features a steering wheel control output for Pioneer, Sony, Alpine, Clarion, Kenwood, JVC, and Blaupunkt aftermarket head units. The steering wheel control output consists of a right-angle 3.5mm connector and a light blue/yellow wire (use the connection that your aftermarket head unit is fitted with). The SWRVW-52 interface module will work with any of the listed aftermarket head units, by setting its three dip-switches (see owner's manual for appropriate setting).
Note: The steering wheel control harness features two 4-pin connectors, two 3.5mm connectors (labeled Pioneer/Sony and Alpine/Clarion), and one blue/yellow wire (labeled Kenwood/JVC). You will only plug in one of the 4-pin connectors to the interface module and one of the 3.5mm connectors or blue/yellow wire into your aftermarket head unit you are installing.
Navigation Outputs: The CRUX SWRVW-52 radio replacement interface module provides a VSS (vehicle speed sense) and a Reverse Gear output to make installing an aftermarket Navigation radio simpler and less time consuming.
Amp Turn-On: The CRUX SWRVW-52 provides an amplifier turn-on lead for your vehicle's factory amplifiers (if equipped).
RAP: In most vehicles your aftermarket head unit will continue to operate with the vehicle's RAP (Retained Accessory Power) system; the aftermarket radio will stay on until the key is fully removed from the ignition switch. However, in 2010-up vehicles with premium sound the RAP feature will not be retained; the radio will shut off when the key is turned off
Wiring Harness: The included wiring harness features a 40-pin connector which plugs into your vehicle's factory radio harness, plus a 12-pin connector which plugs into the SWRVW-52 interface module. The wiring harness also provides the following bare-wire leads which will need to be hardwired to your aftermarket head unit's wiring harness.
