PYT: how to set symbology on output feature class?

$

Ok, I'm stumped (again!)... If I comment out my output parameter this works great and I have point features in my FC, but I need set the output symbology with a lyr file. If I keep the code the way it is the layer is added to the TOC, but no features are inserted to the FC.

You can really ignore most of this and just know that after the insert cursor I have the expected data (gps points).

Any ideas?!!


Code:

import arcpy
import re
import os

class Toolbox(object):
    def __init__(self):
        """Define the toolbox (the name of the toolbox is the name of the
        .pyt file)."""
        self.label = "GPS Isolator"
        self.alias = "GPS Isolator"

        # List of tool classes associated with this toolbox
        self.tools = [isolateGPS]


class isolateGPS(object):
    def __init__(self):
        """Define the tool (tool name is the name of the class)."""
        self.label = "Get a track"
        self.description = "this will pull out one officers gps track..."
        self.canRunInBackground = True

    def getParameterInfo(self):
        """Define parameter definitions"""
