Thanks for all of your attention to this. I do have an audio jack between the two USB ports - I went and looked - faulty memory....
In looking through the manual as well as the separate Infotainment System booklet, under Portable Audio Devices it says: "An iPod, iPhone, MP3 Player, a USB flash drive or a portable USB hard drive can be connected to a USB data port located at the front of the center console or inside the center console storage compartment. To play a device, touch Audio on the infotainment screen; and then touch USB from the Source list or touch More to view the USB option." Scrolling through does not get me to USB on the Source tab by the way.
It is not noted as being an optional feature, so it would seem that this is in this car. The device that I am attempting to use is run off of a USB plug, thus my assumption that the car would play through this player, as well as Amazon stating that this unit would work in this car. In the booklet, there is no mention of the audio plug, so I did not realize that this was an input plug, which the device that I am trying to use does not have.
So, I am confused as to what the booklet says and what is happening, or not happening, here. I am going to the dealer Monday for this as well as a suspected suspension problem, so I will ask them about all of this. If the audio plug turns out to be the only way to go, then one of those players using those is a hundred bucks cheaper, so maybe there is a silver lining in all of this.
Thanks again for everyone's time on helping me with my problem here.
