Dears,
I have a nuvi 3750 a nuvi 255W and a GMT-25 cable.
Was able to get the unlock codes and insert BR Navteq subscriptions.
Worked fine in Sao Paulo area on 3750 , but as already known from this forum didn't worked on 255W, as it doesn't uses TrafficProvider.xml
My question is : Is it due to device software or the GMT-25 is not compatible with nuvi 255W at all ? If it's only software , maybe there is a mod firmware around that can fix it. or not?
Thanks
