USB device requirements

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.

2.0 High speed USB capable (maximum speed is 480Mbps)
At least 256MB storage capacity
USB formatted to be compatible with Windows-based operating systems
If the USB has a security feature, like write protection, it must be turned off

There are many different USB drives, manufacturers, and configurations with new devices being released every day, which makes it impossible to test all USB devices with the audio system. Even if the USB device has all these requirements, it may not be compatible.

To check if a USB device is compatible with the vehicle, test the USB device in a known-good vehicle of the same model and year. If the USB device does not work on the known-good vehicle, assume that it is faulty or not compatible. A USB device may work on a later year of the same model vehicle because the audio unit software is constantly updated.

The audio unit displays the folder differently than what you may see on your PC because the audio unit only recognizes two folder levels. The audio unit overwrites the data for the track order when you connect the USB device. The audio unit does not modify the music files or the structure on the USB device.

Hard drives do not support overwriting the data for the track order, which is why they are not recommended.
