Hello took a trip this past weekend in a friends car which created and "in car wifi" (cadillac cts). He said it came with the car; it does cost him but he says its bundled with his business. Anyone have a similar set up in their car? ifso what unit are you running etc. Now a little info incase you are asking why do you need it if you have a cell phone. I currently have a iphone 3gs and once I was in the wifi it was much faster and streaming of movies was instant. Not really interested in stuff streaming for me however for passengers on long trips it would be nice to have this.
