Chicago - Dec 21, 2011 - Navteq introduced Navteq Traffic over HD Radio, a means by which real-time traffic information is made available to Garmin digital traffic devices. Navteq can now deliver traffic updates approximately every 30 seconds across the United States (wherever HD Radio transmissions are available). According to Navteq "the ultra-rich transmission is 4 to 10 times faster than other traffic services."

The new Navteq service is included with the Garmin Nuvi 3490LMT, and is also compatible with other selected Nuvi devices via the Garmin GTM 60 adapter.
