I got it to run on the N810 by using running Wayfinder first and using the gpsd server option. Without wayfinder running the apps running after the grep are /usr/sbin/gpsdriver and with Wayfinder running /usr/sbin/gpsdriver /usr/libexec/navicore-gpsd-helper /usr/sbin/gpsd -n -N -F /tmp/.gpsd_ctrl_sock /dev/pgp
