I have not heard anything about a radio with wi-fi, as i think of it
But, i have not seen the radios in the 2011 Rams
Chrysler/Dodge & many other car makers offer wi-fi, but it is through the cell phone or another communication device, like blackberry, etc.
I have internet Wi-Fi in my Ram, i just need to connect up my laptop wirelessly to the installed unit, called AUTONET, i can do anything that a person can do in their home online with it. http://www.autonetmobile.com/
