I always buy Nuvi not in Russia. But traffic work fine in Russia on this devices!
But I see some devices from russian distributor with Navicom traffic record in traffic service record. It is exclusion and is not rule. Most of device what Navicom sell not have this record. Traffic is work in any case. For example there are device like that have preloaded map of Europe. No human influence for it after robot-placer.

In one's time I saw on forums the way to convert data like 1001 26/43 into the parameters (FID, PID ...)?!
