Testing & Verification
1. Turn the ignition on. The LED on the interface will turn on & the +12v accessory wire will turn on.
2. Turn on the radio & check balance & fade. Note:
Factory amplified Systems
will not fade as neither the aftermarket radio
or the RP interface have the ability to control the amplifier’s fader.
3. Verify that the factory subwoofer (if present) is playing
4. Verify that all SWC are functioning properly.
5. Turn off vehicle & remove key. RAP will be active & keep the radio on for up to 10 minutes (depending on the user
programmed vehicle setting) or until the drivers door is opened.
6. The LED & radio will turn off when RAP turns off or the drivers door is opened.
Additional Controls
When replacing the radio in the following vehicles you may lose some of the climate control features that the factory radio provides:
Grand Cherokee, Cherokee, Ram & Durango. The RP4-CH21 retains those features by integrating them into the existing factory
buttons and displaying the information on the DIC. PLEASE NOTE: The DIC must be set to Audio mode in order for the HVAC
information to be displayed.
The following buttons have been re-purposed from their original OEM function to retain key HVAC controls that are missing when
removing the factory radio:
• Mute Button - Sets Max A/C On/Off
• Enter Button - Locks out rear zone climate controls (Durango only)
• Screen Off Button - Sets fan position (Defrost/Vents/Floor)
• Back Button - Syncs temperatures for dual zone climate controls
• The lock buttons on the doors control their respective seat heaters. Press and hold lock for 2 seconds to engage seat heater.
Press lock again to change from high/low/off. The status will displayed on DIC.
