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?!!
