I ran the file CenRut.org version 2.4.exe. It placed the files in C:\MyMaps\CAR. I am familiar with MapSource, and already have MapSource 6.13.7. (Also, I do not have Garmin Trip & Waypoint Manager, since I did not need it with my previous Garmin Quest GPS. I only needed MapSource. I now have a Nuvi 2450.) MapSource does not recognize any of the files in C:\MyMaps\CAR. I am not very familiar with CenRut, and do not know how to continue. I plan to travel to Costa Rica.
