Hi Rick,
I have one that I can sell you. $300 shipped. If you are interested I will send you pictures. I only needed two and bought a set of four.

I tried this with my iPhone in tethering mode and couldn't get it to work. If you have an air card or a phone in hot spot mode, I don't know why you would need to go through the car's system anyway.
I am interested in all 4 of them. email me at steelrain7@hotmail.com and let me know how much you want for them. I can drive up this weekend and pick them up.
Danny
