Purchased the Panama Map for my Nuvi 200 and was in Panama for two weeks.  Rented a car at the airport and fired up the Garmin and had a stress free two weeks letting Steve's GPS program guide me around.  Spent my time around Panama City, Coronado and Gamboa and had no problems.  If I missed a turn in the city's many one way streets the program recalculated and got me to my destination, same with Casco Viejo.  The program has many hotels, landmarks, etc. which work a lot better than trying to work with civic addresses in finding a location.  I could not find Gamboa Resort as a locaton on the program but if you use "Summit" you get there, and for the Sora - Altos del Maria area use Coronado and you get there.  Great support from Steve in getting the program downloaded and running.  A definite "MUST" for a trip to Panama,
