TDS GTNxi 650 w/Cessna 172 fails to control the gps data

[plferguson]

I'm new to the environment and don't use SPAD, however, I made the edits in MSFS Developer Mode/Behavior and it disabled the GPS units and the TDS Gtnxi650 worked perfect with horizontal guidance.  I did not see the glide slope show up in the PDF.

Is the TDS software design to set these variable or do I need to set them on each plan I fly and how is that best accomplished?
