If it helps here's what I get on the 810 with wayfinder started:

ps | grep gpsd

1102 root 2132 SW /usr/sbin/gpsdriver
1494 user 15024 SW /usr/libexec/navicore-gpsd-helper
1499 user 2776 SW /usr/sbin/gpsd -n -N -F /tmp/.gpsd_ctrl_sock /dev/pgp
1501 user 1888 RW grep gpsd

once I close wayfinder, and run again I get

1102 root 2132 SW /usr/sbin/gpsdriver
1505 user 1888 RW grep gpsd

If I start mapper ( with filepath /dev/pgps option, and trying to enable gps ) I get only:

1102 root 2132 SW /usr/sbin/gpsdriver
