Hi Mark,
The CW25 is the model number of the little circuit board, but the model
number for the GPS module itself is CW12. So if you search google for
, you'll find the user's manual for the CW12. At
least, it's the version that emulates the Motorola M12.

After upgrading the firmware in my CW25, I took a look at the new firmware .bin
file and found what looks like some undocumented / new messages and parameters.
I sent it requests for the unknown parameters and got back these strings:
$PRTHR,PPSO,0,0,10*51
$PRTHR,MCNO,30*40
$PRTHR,IDNO,00*40
