Appearently the loss warning no longer is acceptable to DOT. It appears that RDK, only one I found in the German price list, is the one accepted by Uncle Sam. Although, the loss warning may still be available and activated if the SCN coding requirement doesn't interfere with it. IC and EIS seem to require this and might prevent activation of non-standard features now.
