Reading the reviews at amaz leads me to search for other opinions. (We already have the Garmin Nuvi, I'm thinking about the add on Travel Guide.)
What we're looking for is something to assist us when we're walking around, in essence asking the Garmin, "what's this".
We prefer not to have a guide book out all the time, or even follow a map when in certain cities.
Your thoughts would be appreciated, positive or otherwise.
