This article deals with the concepts of classic map compatibility and import 3rd party maps.
As Memory-Map has evolved, so has the concept of licensing maps. Two issues that can be confusing are the classic map compatibility and import of 3rd party maps.
Classic Map Compatibility - Classic maps are unencrypted maps (usually older maps). If you purchased maps prior to the new registration system (when you created a user ID and password), they most certainly fall into this category. If your maps are shown in your license list (as a resource), they do not fall into this category. Activating the Classic Map Compatibility resource enables you to use these older maps on the Android.
Import 3rd Party Maps - This feature allows you to use self-scanned maps, GeoTIFFs and BSB charts which have been converted from another format to our QCT format. In most cases, if you calibrated the map yourself, you have the license already.
Both resources can be purchased through the License Management system or via this LINK.
