Product Research


Overview: The PAC SWI-CAN Steering Wheel Radio Control Interface is an add-on module for use with the PAC SWI-RC steering wheel control interface (541SWIRC, sold separately) when installing a compatible aftermarket radio into select vehicles that feature steering wheel controls. It allows you to keep steering wheel controls that use a dual wire CAN bus to control the factory radio. The SWI-CAN interprets and converts steering wheel control data to signals the SWIC adapter, allowing you to replace your factory stereo with an aftermarket deck and continue to use your factory steering wheel controls.

Rotary Switch: The SWI-CAN interface has a rotary switch that needs to be adjusted to match the vehicle it is being installed in. The rotary switch has settings from 0 to 9.

Connections: The SWI-CAN interface has an attached 3" eleven-pin harness that plugs into the optional steering wheel adapter (SWI-RC) which is sold separately. The interface also contains a female 11-pin connector on the other side of the interface that the supplied detachable 7" harness, using the 11-pin male connector end, plugs into. On the other end of this same harness is a 6-pin plug that plugs into an optional C2R interface (sold separately) which attaches to the vehicle's factory harness. If you do not use the optional C2R interface you can also hardwire this connection to your vehicle's factory wiring.

Note: There are 6 bare-tinned wire leads coming out of the detachable 11-pin harness that are not used. There is a sticker wrapped around these wires stating - "These Wires Not Used For Steering Wheel Interface!"

Wiring Advisory: You'll usually have to hardwire this adapter into your vehicle's wiring. In most vehicles, the factory radio plug does not have a wire dedicated to the steering wheel audio controls, so splicing & soldering is often required. PAC does provide custom wiring instructions for all confirmed compatible vehicles on their website.

Probably not needed

Crutchfield Customer Review (What's this?)

I'm returning this. It turns out I didn't need it, as everything was handled with the combination of the PAC-SWI-PS and the PAC C2R-VW2 on my '08 Eos.

I'm giving it a neutral 3 stars because of this.

This is required for VW/Audi cars!

Crutchfield's "accessory" list didn't include this item on my list for my 2006
Jetta GLI install, but you must use it with the SWI-JACK to get the system
to function. The instructions are HORRIBLE and confusing but a 5-minute
call to Crutchfield's techs made me realize how easy the actual install is.

Think about it, and read the manual!

Written By Greg, Louisville on Monday, July 07, 2008

although it did work
on my car (08 GTI),
I basically couldn't
use the right side 4
buttons because they
ALSO would be
navigating the MFD
in the dash at the
same time.
Although it is
stated in the manual
I didnt know it till
it was installed.
Because when you
remove the stock HU
you loose the 3rd
page of the MFD that
WAS for the radio.
So I gave up on
having the wheel
buttons for now and
will wait till they
make a REAL TRUE
interface that will
keep ALL controls as
