With the help of this plugin it is possible to either enter a specific coordinate (e.g. from a text file) or to select a layer whose CRS is unknown. This coordinate/layer is then reprojected from the coordinate systems defined in a list (currently available: "Austria", "All" and "Custom") into the freely selectable output coordinate system and the new layer is automatically loaded.

With the help of a background map the best placed point or the best placed layer extent can now be determined and the correct coordinate system for the unknown file can be read from the attribute table.
