Sorry for the late reply, I have not been in this discussion group for a while.  QNX does ship a keyboard definition 
table for the US and for the German keyboards.
You will need to copy the German keyboard definition file from the SDP installation to your target.

For complete instructions see:
http://www.qnx.com/developers/docs/7.0.0/index.html#com.qnx.doc.neutrino.utilities/topic/d/devc-con.html

and search for the section titled:

"International keyboard layouts"
