TomTom's 3G data-based service HD Traffic is now available to Kiwis who are unwilling to spend upwards of $600 on a GPS unit.
The service, which warns GPS users about reported incidents on the roads ahead, is now available on TomTom's newly-released Go Live 820.
The device is SIM-enabled and runs on Vodafone's mobile network, but rather than having to purchase data, users buy a one-year subscription to TomTom Live that has data included.
The SIM is in-built and not removable.
TomTom's Asia-Pacific vice president, Chris Kearney, said the service was designed to assist city-dwellers in their daily commutes.
"By highlighting areas worst affected by congestion, we hope to ... enable people to consider alternative routes and departure times," Kearney said.
"Traffic congestion is a billion dollar industry in Auckland alone."
The TomTom Go Live 820 has an RRP of $399.
