Frequently Asked Questions

How much will the service cost?

Most compatible in-dash and portable GPS systems offer ‘lifetime’ access to SUNA traffic updates at no extra cost (license costs are incorporated in the purchase price). And because these systems leverage our digital (RDS-TMC) traffic information broadcast, no carriage or mobile phone charges apply.

If you access SUNA content from a Smartphone or portable navigation device that uses a mobile internet connection, then data charges may apply.

Look up your device on our product listing for further information, or for detailed information on devices and costs, please see your preferred electronics retailer. Please click on the link and select your preferred brand for information on specific devices:

Can I get SUNA Traffic Channel for my current Navigation System?

Some navigation systems are able to be adapted to receive SUNA Traffic Channel. Please check with your individual user manual or with your navigation supplier or manufacturer.

If your navigation system comes with the SUNA Traffic Channel RDS-TMC as standard “in the box”, no additional hardware is required and the SUNA subscription runs for the lifetime of the device (subject to the terms of the end user license). Most dedicated navigation devices are in this category. The device should be receiving live traffic updates automatically. Please refer to your device manual for further information for your specific device and settings. Please check to ensure that you are in a broadcast area by checking our coverage map.

If you are confident you are within a broadcast area and still require further assistance, please refer to the retailer of purchase.

If your navigation application operates on a smartphone, you may require an additional subscription to receive SUNA Traffic updates.

Additional subscription models may be introduced in the future to meet the needs of the next generation of devices capable of receiving SUNA Traffic Channel.

If you have upgraded your device by purchasing a TMC accessory or antenna, you will need to ensure that you have the correct version of maps installed. Please check against your specific device for further information.

How does SUNA GPS Traffic Updates work?

SUNA GPS Traffic Updates encodes and silently transmits information to navigation devices which then display this information as warnings or other messages applicable to your location.

Depending on the device, it will either re-route you, present you an option to re-route or display as information only.

Does the “life time subscription” for my device mean I pay nothing to SUNA GPS Traffic Updates?

SUNA GPS Traffic Updates will not charge you any further costs once you have purchased a device if the service comes “in the box”, or if you have purchased an accessory upgrade.

What is SUNA Traffic Channel?

SUNA Traffic Channel is real-time traffic updates for navigation systems.

SUNA Traffic Channel can give you more value every day, on every trip from your navigation system by helping answer questions like: How long am I delayed; Should I detour; When will I arrive; What is causing this jam?

SUNA Traffic Channel broadcasts real-time traffic information directly to your navigation system. Armed with this incredible knowledge of real-time road conditions, your compatible navigation system can inform you of conditions ahead, and recommend routes that minimise congestion. Check here to see if your navigation device is compatible.

With SUNA Traffic Channel, your navigation system can add value every day. By providing you reliable and up-to-date information, you will be better informed, find motoring less frustrating, and by avoiding severe and unexpected congestion you may even arrive sooner!

I have intermittent reception. Why?

Please check that your antenna is connected and properly positioned. Confirm that you are in a broadcast area. If you are in a poor reception area (many things can affect FM reception such as tall buildings, the landscape), try again in a different location.

If you are still experiencing difficulties, please contact your device manufacturer for technical support.

Why should I buy a SUNA Traffic Channel enabled device?

As congestion grows, so does frustration. Having information beamed directly to your navigation device will help you plan your journey, and know about likely delays before they happen.

What devices is SUNA GPS Traffic Updates available on?

The SUNA service is available on many navigation systems; please select your preferred brand for information on specific devices from the list here.

Will SUNA Traffic Channel work all of the time?

Suna Traffic Channel operates 24 hours per day, 365 days per year with the best quality transmission possible.

To check the service status in your region please click here.

If I buy a navigation system overseas, will the provided traffic receiver work in New Zealand?

This is device dependent. We provide the SUNA service to those manufacturers with whom we have a commercial agreement. There may be a way they can provide you with access to our service via a unit purchased overseas but you would need to confirm this with your preferred brand.

If I purchase a SUNA GPS Traffic Updates enabled device in New Zealand, will it be enabled to also receive and decode Traffic updates when I take it overseas?

The service supplied by our overseas counterparts differs from country to country, and you would need to ensure that you have the relevant maps, and hardware required to access their services. In order to check specific requirements for your device you should go to the device manufacturers’ website for further information.

Is SUNA GPS Traffic Updates compatible with my device?

SUNA GPS Traffic Updates are now available in Auckland, Wellington and Christchurch metropolitan areas. We are continuing to talk with all areas of the automotive, navigation and mobile phone industry. SUNA Traffic Channel is provided via a subscription based service as an encrypted transmission, and as such the receiving devices need to be capable of decoding the information. Devices capable of decoding this transmission are available from those companies with which we have a commercial agreement (please check here for specific device information).

If I spot an incident, how can I let SUNA know?

Suna GPS Traffic Updates is very grateful for the feedback and notifications of traffic conditions being provided to them from motorists. This helps make the service more accurate for all road users. The best way to provide this information to Suna is by going to the website’s contact us section and selecting “report traffic experience”. Alternatively, follow this link. If your preference is to report your experience via the phone, the number to contact Suna via the phone is 1300 00 SUNA (1300 00 7862).

What information will I receive through SUNA Traffic Channel?

Traffic information is comprised of three main components:

  • Where it is? – location. Messages that provide information about speed reductions or delays are most common. Where known, the cause of unexpected delays is explained (NB: no cause is given for routine or ‘peak-hour’ congestion). This explanatory information is provided to help you judge the significance of a delay.
  • What the impact is – eg speed or delay. Coupled with your navigation device, only relevant information is drawn to your attention.
  • What the cause is – eg accidents, road works, lane closures. The international TMC standard enables us to broadcast messages with a certain ‘granularity’ or geographic resolution. Generally, the finest resolution that can be supported for messages on arterial roads is between intersections with other main roads where there are traffic lights. This works fine for navigation purposes, but explains why a traffic event may show across a length of road between intersections, even if it is really only at a point along the road.

Why does it take more than 5 minutes to load all the messages when I first switch my device on in the morning or evening?

As with any device that receives information, it can take time for all messages to be picked up. At peak times there can be as many as 300 messages being transmitted, and as such your device will systematically register the information it receives as it processes the data.

In addition, please check that your antenna is connected and properly positioned. Confirm that you are in a broadcast area. If you are in a poor reception area (many things can affect FM reception such as s tall buildings and the landscape), try again in a different location.

Will traffic always work?

Intelematics aims to provide the highest quality service possible, however, we will schedule maintenance during periods of the year. Please check our service status website for more details.

Why didn’t traffic tell me to re-route?

Navigation devices will advise you of rerouting if there is an alternative path available. This is dependent on many factors including any personalised options you may have set on your device. Check with your device documentation for the best settings for you.

Do I have to tune my car radio to an FM frequency to receive the SUNA GPS Traffic Updates?

No, compatible GPS devices have a separate FM receiver built in to receive the SUNA GPS Traffic Updates

Will the SUNA GPS Traffic Updates broadcast interfere with my car radio?

No, compatible GPS devices have a separate FM receiver built in to receive the SUNA GPS Traffic Updates.

I could not receive traffic reports on my device today – is there a problem?

As SUNA is broadcast using FM technology occasionally devices may experience drop-outs. Occasionally black spots can affect transmission, especially in very dense urban areas such as CBD, and terrain effects, (e.g. valleys).

For portable navigation devices the correct placement of the antenna will also minimise the chance of drop-outs. Please refer to the hardware manual for further information.

For current service information please visit our Service Information page.

Where will traffic work?

SUNA traffic updates are available in the metropolitan areas of Auckland, Wellington and Christchurch.

Please take a look at the coverage maps to ensure you are in an area which receives traffic information.

How do I know if I am receiving the SUNA GPS Traffic Updates Broadcast?

Suna GPS Traffic Updates is broadcast using a normal FM radio signal, so you can easily check for reception by tuning your car radio to the same frequency. If you have good audio quality, you should generally be capable of connecting to SUNA Traffic Channel. To check the service status in your region please click here.

Occasionally, as with all FM reception, brief drop-outs may occur – don’t worry however as your navigation system will store hundreds of messages.

NB: If you have a portable navigation system, correct use of the antenna is important – please refer to your navigation user manual.

Can you please tell me the frequency my device should tune into. I am unable to receive your broadcast and want to verify reception via car radio.

The current frequencies are:

  • Auckland – 97.4
  • Wellington – 90.1
  • Christchurch – 97.7 & 96.5

It is generally not advisable to manually lock the device onto a single frequency as receivers are designed to automatically search other stations carrying the SUNA service. Also if the frequency changes, or you travel to another city, the unit may not work. If you continue to have difficulties with the unit automatically finding the frequency, please refer to the retailer of purchase your device manufacturer.

Why isn’t my device picking up traffic?

Check that your antenna is plugged in and the location of the device in your vehicle. Check with your device manual on how to ensure that it is tuned to the correct transmission. For transmission information please check here.

Please note window tinting can affect the transmission being received.

I have intermittent reception. Why?

Please check that your antenna is connected and properly positioned. Confirm that you are in a broadcast area. If you are in a poor reception area (many things can affect FM reception such as tall buildings, the landscape), try again in a different location.

If you are still experiencing difficulties, please contact your device manufacturer for technical support.

Where will traffic not work?

Your GPS device will receive traffic information within the areas that we transmit in metropolitan Auckland, Wellington and Christchurch. Please take a look at the coverage maps to ensure you are in an area which receives traffic information. Some device manufacturers do not offer the service in all the areas it is currently available, For more information, please check against your navigation brand manufacturer:

Will SUNA Traffic Channel work all of the time?

Suna Traffic Channel operates 24 hours per day, 365 days per year with the best quality transmission possible.

To check the service status in your region please click here.

Where does the information you transmit come from?

We currently generate our traffic data from a number of sources. In particular we receive incident data from City Councils; we also employ our own traffic information operators who enter incident data into our system; staff monitor CCTV cameras and compile information from other sources on road closures, e.g. festivals parades etc, as well as road works and other information that can impact traffic; we receive automated feeds of information from the sensors in the road that are used to control traffic lights in capital cities; and to assist in fine tuning our service, we also employ quality management personnel.

What do the messages mean?

The international standard enables us to categorise congestion according to precise rules. Once you are familiar with SUNA GPS Traffic Updates, you will find a high degree of consistency. Here are some tips on what to expect with the most common.

On Freeways:

Congestion: We generally broadcast speed messages in steps of 10kmh. We begin broadcasting when speeds drop to around 50% or more of permitted speed. ‘Stationary Traffic’ means crawling below 9kph. Each speed message is an average measure between freeway junctions.

Incidents: We broadcast the type of incident e.g. accident, road works, special event etc, along with the expected length of delay.

On Arterials:

Congestion: Most delay occurs at intersections, so “average” speed takes into account the time stopped at lights, as well as the actual speed while moving. When we detect serious congestion, we issue a message representing this average speed, or where possible we advise the likely delay instead of speed.

Incidents: We broadcast the type of incident e.g. accident, road works, special event etc, along with the expected length of delay. SUNA GPS Traffic Updates is broadcast using the international standard for real-time traffic, ‘RDS-TMC’. We silently encode the SUNA information in a normal FM radio broadcast. Radio listeners hear nothing, but special TMC receivers decode the information and pass it to your navigation system.

Why does the reception keep dropping out?

SUNA is broadcast using FM technology – occasionally black spots can affect transmission, especially in very dense urban areas such as CBD, and terrain effects, (e.g. valleys). Correct placements of the antennae will also minimise the chance of drop-outs. Please refer to the hardware manual.

I’ve plugged in the antenna as per the instructions but nothing happened. Is there something else I should do?

If all the elements on your device are correct, on the first instance of accessing the SUNA service, it may take up to 20 minutes for the device to pick up. This should occur on the first instance only.
