Adjust the Volume on a Chrysler Uconnect Navigation Device with Garmin Navigation

To adjust the volume on a Chrysler Uconnect navigation device, the navigation must be in an active route to a destination and giving voice prompts.  A voice prompt can be initiated by touching the directional indicator in the upper left corner of the navigation. When the system is giving a voice prompt, use the volume knob or volume buttons to adjust the navigation volume.
