This feature allows you to plug in an iPod into the
vehicle’s sound system through a connector (UCI connector)
using an optional connection cable (available
through Mopar). See your authorized dealer for details.
Using this feature,
- the iPod audio can be played on the vehicle’s sound
system, providing metadata (Track Title, Artist, Album,
etc.) information display on radio.
- the iPod can be controlled using the radio buttons to
Play, Browse and List the iPod contents.
- the iPod battery charges when plugged into the UCI
Connecting the iPod
Use the optional connection cable to connect an iPod to
the vehicle’s UCI connector (which is located in the glove
box on some vehicles. This location may vary with
vehicle). Once the iPod is connected and synchronized
to the vehicle system (this may take a few seconds to
connect), the vehicle brand logo appears on the iPod
display, and it starts charging and is ready for use by
pressing radio switches as described below.
Controlling the iPod using Radio Buttons
To get into the UCI (iPod) mode and access a connected
iPodt, press the “AUX” button on the radio faceplate.
Once in the UCI (iPod) mode, the iPod audio track (if
available from iPod) will start playing over the vehicle
