Civil 3D 2010 and xrefs

When I bring an xref/raster image into my drawing At 0,0,0, coordinates, it is quite a distance away from where it should be. I would guess that it is not the xref but the drawing that is the problem. I have checked my state zone and what unit of distance used to bring in my survey points and both are correct. What could I be overlooking that might cause this to happen.

Firstly your xref could be at one set of co-ordinates and your survey at another hence both aknowledge 0,0,0 but are apart, check the xref co-ords and check for ucs W.

 

Secondly you can bring images in two ways a nice jpg picture or georeferrenced as world ground co-ordinates and true scale again you would need to find out which you have.

 

But Like Alanjt check all the drawing settings first in both drawings ! is one set to unitless and the other metric m this is a scale factor of 1000 straight away.
