No, the traffic receiver is built in to the supplied power cord. I have been using mine in the SF Bay Area for about a year now. The traffic information is not as up to date as it should be, a little slow to tell you bad news, very slow to remove it. Sometimes it will tell you roads are gridlocked several hours after they have cleared.
