If that's not the manual for the version you have, please either lower your mind-reading firewall a bit, or give us a clue as to what device you actually have
Good question, l have no idea as there is no info on the front panel or in the completely Dutch manual. 1991 is all l know! The link didn't appear, sorry prv. I'll have a look at those 'talkers' though. Thanks
Based on the AP8, NMEA out (talker) +ve is pin 3 on the D-sub. Pin 8 is the NMEA out -ve. If connection to pin 8 doesn't work, try pin 1 instead, which is ref. gnd.
You won't blow anything up if it's wrong, (I think!!)
Other AP Navigators might be different of course.
