ST.W.BED. Jeep/Chrysler/Dodge + oem Amp retention

wiring interface lets you replace the factory radio in select 2005-20 Chrysler, Dodge, Jeep, Mitsubishi, Ram, and Volkswagen vehicles. You'll retain your factory steering wheel audio controls, your vehicle's entertainment system, and the use of your factory amplifier, if present.

Another plus — the RP4-CH11 interface eliminates the need for the secondary steering wheel control interface (SWI-CAN or SWI-CAN2) that's usually required for these Chrysler-built vehicles, saving you some more cash. Warranty: 1 year.

Important Note: If you have a factory amp in your vehicle, you'll lose the ability to fade from front to rear when you install a new car stereo. (See Details.) See Details for a list of compatible car stereos.

Inside the package

• Radio replacement/SWC interface module (for Chrysler/Dodge/Jeep)
• A harness (13-pin to 10-pin connector + bare wires)
• B Interface harness (15-pin to 10-pin connector + bare wires)
• 12" Steering wheel control harness (4-pin connector to 3.5mm/blue wire)
• Instructions.

compatible with select 2004-up Chrysler, Dodge, Jeep, Mitsubishi, and Volkswagen vehicles with the CAN-bus system. Compatible vehicles as of 7/13/2016 include:

Radio Select Switch: The radio select rotary switch on the side of the interface must be adjusted to the proper radio setting before plugging the interface into the vehicle.

Amplified & Non-Amplified Factory System Compatible: The RadioPro4 (RP4-CH11) is compatible with both amplified and non-amplified factory systems.

• Vehicles without a factory amplifier: Connect the aftermarket radio's front & rear speaker wires to the vehicle connector.
• Vehicles with a factory amplifier: The factory amplifier only accepts two channels of audio input (left/right). Connect the front outputs of the aftermarket radio to the rear inputs of the vehicle connector. This will allow navigation voice prompts and Bluetooth calls to be heard. The rear speaker outputs of the aftermarket radio are not used. Fading is not supported in this application. The factory amplifier's fading is controlled by data communication from the factory radio. Neither the aftermarket radio or the interface have the ability to control the amplifier's fader.

Wiring Connection Chart: Only one of the two provided radio harnesses will be used.

SWC Compatible: The interface comes pre-programmed for all of the vehicle's factory SWC functions and does not require programming, unless you wish to re-assign the SWC functions to different buttons. The SWC functions can be easily programmed; see control settings and functions below.  The interface retains programming even if your vehicle's battery is disconnected.

Note: The SWC harness contains a Blue/Yellow wire and a 3.5mm connector. You will only use one of the connectors, based on your type of aftermarket radio. The Blue/Yellow wire supports Kenwood, Newer JVC, OEM and Blaupunkt radios. The 3.5mm jack supports Alpine, Jensen, Older JVC, Clarion, Pioneer, Sony, Valor, and Dual radios. Not compatible with Soundstream head units.
