I was reluctant to purchase the map for Costa Rica but I made a good choice in doing so. The map was accurate all of the time except for 2 times, in a week of travel. Once the map took me to a road that didn’t exist the other time it couldn’t find a restaurant (it was open for only 2 months. You have to use points of interest in Costa Rica and just enter the name (park, restaurant, etc ) and your GPS will get you there. Excellent customer service. I had questions about downloading the map and got immediate responses to my questions. Highly recommend the map. BTW Hertz wanted $12 per day for their GPS.
