Phil messaged me back and said that some have reported this while others have not.
So, this is what I did:
I ran the blk/brown cable from blk HMI to brown usb inside the console. This feeds the usb hub inside the arm rest area. Checked and car play now works at the usb connection inside the arm rest area.
My next thought was to run the green HMI to the input on the double usb connector of the front upper console part, and run the output to the usb in the glove box. This meant I would need the grn/gray cable, but I had purchased the blk/gray cable. And also would need a black to regular USB connector. Not sure if they even make this or not.
But I had some wire cutters!
i cut he blk/gray cable in half, and did the same to the grn to USB from the glove box. Swapped ends so that I ended up with the glove box USB with a black connector on the other end instead of a green. I then plugged the blk end into the output of the double USB hub in the front upper console and the other end into the glove box. I went ahead and ordered a new grn/gray cable, but just to test things out I spliced the left over ends to make a grn/gray cable. Plugged it in from the grn HMI to the input of the double USB hub in the upper front console and now have car play at all three USB locations!
Go figure.
