garmin settings for markfish

 HI All

I have a furuno 628 hooked up to a garmin 952xs plus via markfish , just wondering if anyone has the settings for the garmin as the NMEA 0183 in this newer model and

has bulk settings and options, i know they are connecting in some way as the furuno when i hit the mark button shows the gps position but when i hit enter or mark again it dosen't transfer 

the mark over to the garmin.

I have followed furuno settings from previous posts on this site but am lost for what the garmin should be
