I'm sure Garmin gladly took some money to license their name in the sim, but they sure as heck didn't provide any sort of QA....or event guidance on how to implement basic GPS functionality needed to go /G under IFR. It's baaaaad. Really bad...across the board from the GNS430 through the G5000. If I were Garmin, I'd be pretty upset right now. The good news is that you can use that fancy looking G1000/3000/5000 equipped plane and shoot all the approaches you want /a. ATC has never been great, but they managed to take it from basic but functional to whiskey tango foxtrot. I think eventually they will get Garmin avionics to a better place, but I don't know how long before that happens.
