I believe that is part of the 'notifications' that the Zumo gets wirelessly. If I remember what Garmin said in their manual for another GPS, the antenna for that traffic info was in the cord that powers it. If you change to a generic cord (without the antenna) you won't get that. At one point I got a cheap power cord for my Nuvi from ebay, and traffic notes disappeared. The cord did not last long - the plug literally fell apart, jettisoning the fuse, so I bought one from the Garmin outlet store - that restored my traffic notes in that Nuvi. I'm not positive that the Zumo is the same. The Nuvi's are auto gps devices, not waterproof, not able to download tracks, etc.
