To locate these co-ordinates I found it easier to count back from the start of the following record. The two sets are followed by a further 16 bytes of data -use unknown, which completes the record. Each longitude or latitude value is stored as a double which requires 8 bytes therefore 32 bytes are required to store both sets. In my sample they were either very similar or the same. I speculate that one set is actual and the other set is nearest road.

I have deconstructed the records found within Previous.dat. T his file contains Recent Locations which are locations that the user chose to navigate to.
At the path DestinatorApps\Destinator\UK_Ireland I found Previous.dat. I accessed the device via Mobile Device Centre in Vista and copied off the contents of the ResidentFlash volume. It has an external SD card slot which was not populated on the one I looked at. This device runs destinator software within a Windows 4.2 CE OS and is similar to the Medion MDPNA150 I looked at earlier.
