Many reasons, one of them could be that the old autopilot
doesn't process the standard wind data sentences but only some proprietary crap. That's so popular with those nautical electronic geniuses. Another could be that the autopilot doesn't process NMEA
input at all.
You'd be lucky to find in the old manual the NMEA
sentences the autopilot understands, then you can start looking whether they contain wind-data in any way current
devices are producing.
NB: A quick search on the internet
indicates that this isn't a trivial problem.
