Any maps that you use with the Memory-Map desktop mapping products can be used on your iPhone or iPad. This includes Memory-Map map packages, or any third party maps that are compatible with the desktop product. For example BSB charts, or eTopo maps can be used (NB, this requires the "Import Maps" license).
You can also scan a paper map (with the permission of the copyright holder), calibrate it using the Memory-Map desktop PC app, and use the result for navigation on your iPhone. The map files (with QCT, QC3, MMI extensions) can be loaded directly off your original Memory-Map DVDs.
Maps may be found in the folder C:\Maps or C:\Maps_V5 on your PC hard drive.
To copy the maps to your iOS device, you have to use iTunes on your PC or Mac.
Sync your device with iTunes using the USB cable.
In iTunes on the PC/Mac, select the device, and click the Apps tab.
At the bottom is a section that shows all the apps that support file sharing. Select Memory-Map.
You can now drag-n-drop files and folders into the list on the right.
