10 Audio Auxiliary equipment USB flash drive 10 To simplify the use of a USB flash drive, it is advisable to only store music files on the drive. It will take considerably longer for the system to index the files on the drive if it contains anything other than compatible music files. If the external sound source's volume is too high, the quality of the sound may be impaired. This can be prevented by adjusting the external sound source's input volume. 1. While playing the radio or a CD, lower the audio volume to about one-quarter. 2. Switch to AUX mode on the audio system. 3. Connect the headphone output from your music player to the AUX input using a cable with a stereo 3.5 mm miniplug at both ends. 4. Set your music player's headphone volume to three-quarters using the player's volume controls. 5. Select AUX VOLUME in the menu and press ENTER. 6. Adjust the volume with SELECTOR or with the up/down arrows and press ENTER. 7. If there is distortion, lower your music player's headphone volume until the distortion goes away. NOTE This cannot be done with the steering wheel keypad. The cover over the cup holders should be open when an auxiliary device is connected.

The device must have at least 256 Mb of memory. Auxiliary sound level 254 G027150 Finally, exit the menu and adjust the audio volume to a comfortable level.
