Dave,

Q. Is there any way to operate the A70D with DGPS corrections?
A. Negative. The positional accuracy of WAAS GPS Sensors (Satellite Differential (SD)) has largely eliminated the gains which has once been provided by land base differential GPS beacons. The A-Series Classic MFDs are designed acquire GPS position data via the MFD's internal GPS sensor or from a SeaTalkng / NMEA 2000 or NMEA 0183 source of such GPS data. When using an external GPS source, the MFD's internal GPS sensor should be configured OFF. The A-Series Classic MFDs feature a Chart Offset feature to address georeferencing errors which were not uncommon some chartlets within early electronic cartography offerings. Such issues are quite rare within currently available electronic cartography.
