I don't think it is possible to download waypoints to the GPS12, the serial interface is only used for NMEA transmission and differential GPS (RTCM DGPS) input, however you can enter waypoints manually, see page 20 of the owners manual: -

mmm so did you know is the gps 12 can connect to mapsource or no?

NO, there is no mention of Mapsource in the owners manual, the GPS12 is 24 years old

I updated the gps date and time then map source read it and I sync 370 waypoints to the gps
Thank you so much
