My gal friend has a NUVI 255W.
It is at least 4 years old.
The "lady" inside of it gets very confused sometimes.
Especially when there has been new road construction since the original maps were installed.
I'm not finding the threads that give me specific information on how to update her maps.
I'm guessing that City Navigator NA will do the job.
But, that is just a guess.

Can anyone point me to the threads that tell me how to update the maps in the NUVI 255W in such a way that the "lady" inside the GPS can give correct vocal instructions for navigating around North America?
