You can select the AUX mode by using the navigation system voice control buttons, but cannot operate the play mode functions.
iPods compatible with your audio system using the USB adapter cable are:

Use only compatible iPods with the latest software. iPods that are not compatible will not work in this audio unit.
NOTE:
Do not use an extension cable between the USB adapter cable equipped with your vehicle and your dock connector.
Do not keep the iPod in the vehicle. Direct sunlight and high heat will damage it.
Do not connect your iPod using a hub.
We recommend backing up your data before playing it.
Some devices cannot be powered or charged via the USB adapter. If this is the case, use the accessory adapter to supply power to your device.
In AAC format, DRM (digital rights management) files cannot be played.
If the system finds a DRM file, the audio unit displays UNPLAYABLE, and then skips to the next file.
