External audio source volume
Set the volume for an external audio device. If the external sound source's volume is too low or high, the quality of the sound may be impaired.
If an external device such as an MP3 player or an iPod ® is connected to the AUX socket, the device's volume may be different than the volume of the infotainment system's internal sound sources such as the radio. To help prevent this, adjust the input volume of the external audio source. To do so: From the AUX’s normal view, press OK/MENU. Select and select Standard or Boost.
Note
Sound quality may be affected if the MP3 player is being charged while the system is in AUX mode. To help prevent this, avoid charging the MP3 player in a 12-volt socket while it is being played.
