There is basically only one serious GPS map available for Panama, the one from Panama-Zone.
I bought this map last year for my Garmin Nuvi GPS and at first I had some reservations because the map was pricey, had very limited points of interests, and contained several errors.
However, the team at Panama-Zone are constantly updating their map and have fixed most problems and added thousands of points of interests. It is now a mature and highly useful map, at least for Panama City. It has proved to be a tremendous help for me as I tried to make sense of the streets and neighbourhoods of Panama City, and it has greatly accelerated my learning and my confidence.
I can now Highly Recommend this map to anyone who needs to drive around the maze that is Panama City. It will save you tons of time, reduce your frustration and stress, and increase your safety.
