The same thing happened to me a while ago.  It's old software that didn't 
know about the 1024 week rollover.  Mine was happy after I told it the date.

I used (Linux) this:
  echo -e ":GPS:INIT:DATE 2011,12,26"  > /dev/hpgps1

  I have a note that says it may need to reset UTC mode too.
  echo -e ":diag:gps:utc 1"          > /dev/hpgps1 # Needs reboot?
