Iris F-20 Tigershark GPS

I see from the manual and by looking at the GPS hml file that the stock F-20 GPS should be operational but I cannot get it to power up at all. Everything else seems to work okay but this device doesn't. How does it turn on? If I put my cursor over the power knob, nothing happens to allow me to press it. What am I missing here? I could, like the manual says, just substitute the standard MS/Garmin device in the panel.cfg file but I'd really like to make this thing work so I can edit a flight plane and maybe figure out how the ILS works in this thing. Speaking of that, assuming that I get some kind of GPS working, will the ILS actualy engage and fly the plane down to minimums? I sort of got it to track the localizer in approach mode but it was really sluggish and wandered all over the place. But the glide slope never engaged. Does this function work or do I need to install a Garmin 530 and Trutrak autopilot? (I'm an avionics tech by trade and specialize in L-39s).

Okay I was slightly off in my description of what works and what doesn't. The thing is apparently on but all it says is "no flight plan loaded" and none of the buttons and knobs are active with the cursor.
