Finally..
Thank god I found this app.. I am on a trip to Panama and couldnt find any other good offline maps for it.. I would prefer not to buy a dedicated GPS device as I have my iPhone. I am on roaming so I prefer the maps that stay inside my iPhone and not use 3G. This one has all that I need. I saw some issues with other users but I guess I have downloaded the latest update which is working for me just right.
However if there was an option to use the units in miles, it would be a winner.. Still..a good app to use though..
