Features

Steering Wheel Control Interface: PAC's ControlPRO SWI-CP2 retains the built-in steering wheel controls in select vehicles when replacing the factory radio with an aftermarket radio. It also allows the retention of rear seat controls (RSC) and retained accessory power (RAP) in select vehicles. The SWI-CP2 is compatible with many of today's most popular vehicles, even with more complex electronic systems including CAN bus, GMLAN, and Class II systems. The simple to use interface module can be configured in multiple ways - via dip switches, direct from a USB connected PC, or a button learning procedure. Wiring and vehicle configuration dip switch settings are provided through the ControlPRO APP - available for PC, and Android and iOS devices.

Vehicle Compatibility: The PAC SWI-CP2 steering wheel control interface is compatible in vehicles equipped with CAN Bus, GMLAN, Class II, LIN Bus, I-Bus, and Analog or Serial Data SWC. Compatible vehicle makes include Acura, Audi, BMW, Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC, Harley Davidson, Honda, Hummer, Hyundai, Infiniti, Isuzu, Jaguar, Jeep, Kia, Land Rover, Lexus, Lincoln, Mazda, Mercedes, Mercury, Mini, Mitsubishi, Nissan, Oldsmobile, Pontiac, Porsche, Ram, Saab, Saturn, Scion, Subaru, Suzuki, Toyota, Volkswagen, and Volvo.

Note: Click here for complete list of compatible vehicles.

Programming & Configuration: The PAC SWI-CP2 steering wheel control interface offers 3 programming & configuration methods.

  • Manual Configuration Mode: With this method, the SWI-CP2 uses a pre-determined dipswitch configuration to assign the vehicle and SWC button functionality. The dipswitches on the side of the interface must be manually set to the proper configuration by the user. These vehicle specific dipswitch settings can be found by downloading PAC's ControlPRO application onto your Windows PC (7-up), Android smartphone/tablet (OS 4.0.3+), or Apple iPod touch/iPhone/iPad (iOS 7.0+).
  • App Mode: With this method, the SWI-CP2 can be connected to a Windows PC in which PAC's ControlPRO application assigns the vehicle and SWC button functionality. The dipswitches on the side of the interface must all be set to down/on which is the default position. When using this method, it is not required to manually program the SWC buttons when programming via App mode.
  • Manual Programming Mode: With this method the SWC values must be manually programmed into the SWI-CP2 by using the programming button. The vehicle dipswitches on the side of the interface must all be set to the up (off) position. The radio dipswitches must be set to the proper radio configuration (see Instructions). This mode is only compatible in vehicles with both analog SWC and a discrete 12v Accessory wire; vehicles with CAN-Bus buttons cannot be manually programmed.

Two-Function Assignment: The PAC ControlPRO SWI-CP2 allows you to program two radio functions to each SWC button on  your steering wheel by using short press/long press dual command functionality.

Retained Accessory Power (RAP): In vehicles equipped with retained accessory power (RAP), the accessory output and the red LED will remain active & keep the radio on for 10 minutes unless the driver side door is opened. In vehicles that do not support RAP, the LED and accessory output will shut off when the key is switched or removed from the ignition.

Wire Code Chart: Crutchfield recommends that all wiring connections be soldered to ensure a sturdy and reliable connection.

Q
will i need to buy the METRA 40-EU56? or only this product?
[ Alexander  Aug 04, 2019 ]
1 answer
A
This PAC part is only a steering wheel radio control interface. If we list the Metra 40EU56 antenna adapter for your vehicle, you will need to get the Metra part to get the stock FM antenna working with the new radio along with this part to keep the steering wheel radio controls working with the new radio.

Q
Will this work to connect a wired marine remote to a automotive head unit?
[ jaycee  Aug 16, 2018 ]
1 answer
A
It will not. Sadly, I've never found an interface for that and have had to recommend customers replace the remotes with the the new radio they get for their boat. We have advisors that can make sure you get a new radio that works with wired remotes so this can be done. You can call 1-800-324-9695 to get this personal recommendation.

Q
Is it compatible with OEM premium audio amplifier on 2008 Ram?
[ Chris  Sep 04, 2017 ]
2 answers
A
The PAC SWI-CP2 is compatible with the factory steering wheel radio controls in your truck. As Steven mentioned; the adapter does not interface with the stock amplifier; just the factory steering wheel controls and the compatible aftermarket stereo. For additional assistance and personalized recommendations, feel free to contact us directly: https://www.crutchfield.com/support/ContactUs.aspx
[ Ryan  Sep 06, 2017 ]  Staff
A
It shouldn't interfere with the stock amp. All this unit does is interface your stock steering wheel audio controls so they work with your aftermarket stereo head unit. If you are installing a new head unit, what's when you'll want to make sure you order the wiring harness adapter that will retain use of the stock amp.
[ Steven  Sep 05, 2017 ]
Q
Power Acoustik PD-625B Compatible?
[ Riley  Jun 07, 2017 ]
1 answer
A
Thanks for your question. Crutchfield does not carry that brand of receiver. The ability to retain steering wheel controls with aftermarket receivers will be determined by the receiver you are using and the vehicle you have. For more information on this type of integration (including the parts you will need) please contact an Advisor by phone (1-800-324-9695) or online chat.
