If not, then its not worth messing with it. You can get a hardware based that translate the rockwell to NMEA, they cost more than a decent SIRF3 unit though. If you are lucky you might find a software version of this translator.
To tell you the truth that GPS is crap, I mean real crap. The fix time is like 30 mins I got lost a few times cause of its crap sensitivity and crap fix time. Bin it and save yourself the hassle.
