Description
Description
The PAC RP4-CH21 RadioPRO4 interface supports aftermarket radio installation in select Chrysler-family CAN-bus vehicles. It integrates steering-wheel controls, supported factory amplifiers, the original backup camera and applicable climate functions.
Check retention limits
Examples include 2013–2018 Ram trucks and 2014–2015 Dodge Durango, Jeep Cherokee and Grand Cherokee. Factory uConnect and VES are not retained. With an 8.4-inch uConnect system, the factory compass display, 911 Assist, Wi-Fi hotspot and uConnect Access are lost. Non-amplified vehicles with reverse sensors lose reverse chimes.
Before installation
Some 2016–2018 Ram vehicle settings cannot be changed after installation, and ProMaster applications with a factory single-DIN radio are excluded. Confirm the exact equipment and required retained features before choosing this interface.
