.SPUD File

File extension spud seems to be mainly used for a special file type for GPS navigation apps or devices produced by Mio.

A .spud file contains data used to update positions of fixed speed cams in maps.

How to open:

Possibly can only be used in Mio Navigations to update the program data.

How to convert:

Update or patch files are rarely converted to anything else, so conversion of .spud files to anything else is highly unlikely.
