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.
