• For USB mode, it is not possible to view JPG files on the in-dash monitor while the vehicle is moving. This is a safety
feature to prevent driver distraction.
• The JPG image viewer function will only operate when vehicle is in park and the parking brake is engaged.
• Due to ongoing technological advancement, some USB flash drives and/or SD cards may be incompatible with
this unit.
MP3 playback sequence begins in the root folder of the USB flash drive or
SD card. Any empty folders or folders that do not include MP3/JPG files are
skipped.
ISO9660 standards:
• Maximum nested folder depth is 8 (including the root folder).
• Valid characters for folder/file names are letters A-Z (all caps), numbers
0-9, and “_” (underscore). Some characters may not be displayed correctly,
depending on the character type.
• This device can play back Joliet and other standards that conform to
ISO9660. MP3 written in the formats other than the above may not play and/
or their file names or folder names may not be displayed properly.
Some files may not play or be displayed correctly, depending on sampling
rates and bit rates.
For best results, use the following settings when ripping MP3 files:
128kbps or higher constant bit rate
44.1kHz or higher sampling frequency
