The largest capacity cards Kirsch’s Outdoor Products utilizes for development of Garmin maps are 2GB memory cards. We do not recommend or support having multiple maps on the same card. Some of the reasons include:
- Many Garmin units have a programmed limit of map sizes of 2GB.
- Many Garmin do not allow multiple map sets to exist on one card.
- The update tool and update process would not work correctly if multiple maps existed on one card.
