With their new line of 2012 nuvis, Garmin introduced the 3D Digital Traffic powered by HD Radio. Digital 3D Traffic provides updates every 30 seconds over the HD Radio broadcasting system, which means it downloads data 30 times faster than traditional traffic receivers.
Congestion ahead on your morning commute? 3D Traffic will let you know almost instantly so you can easily reroute. When using other traffic models, you could waste over five miles worth of travel time before an alternate route is provided. Overall, 3D Traffic is up to 10 times faster than other traffic systems on the market. With the new digital traffic, you'll avoid major traffic jams and arrive at your destination on time.
3D Digital Traffic comes preloaded on the nuvi 3490LMT and is compatible with the nuvi 2405, 2505, and 3400 series. If you have a 2405, 2505, or 3400 series nuvi, you can pair your compatible unit with the GTM 60 digital receiver. Its antenna allows you to receive 3D Digital Traffic the same way the 3490LMT does - over HD Radio. Even better, the traffic data is free for life with the GTM 60.
