They've probably switched to a new receiver in the 2000. I'm still working on qualifying a newer module which suppprts the Russian GLONASS in addition to GPS. So far it seems to be a much better receiver all around, but I haven't had the time needed to complete the testing. It wouldn't surprise me to find that it also does a better job in high noise situations.
