Garmin GTN 650/GTN 750 and G1000 installed in our Pilatus PC-12 and Citation Mustang, respectively, have been superb. I’ve never had a problem. Also, I find our Garmin Flight Stream 510 is very useful with iPad.

Love all the Garmin products we have in our aircraft. We just ordered a Phenom 300E and it also has Garmin avionics. One big factor in the decision to purchase the Phenom 300E was the avionics. Garmin made the sale.

I have Collins Pro Line Fusion installed in our Legacy 500, and Garmin G3000 in our Phenom 300. I think both are good, but prefer Collins 100% over Garmin. Garmin is like an iPhone, while Collins is more for professional pilots.

As I manage the airplane, I make sure the avionics and airplane are well taken care of – ie, check hangar humidity, crank engines, APU, and avionics – at least once a week when the airplane is not being flown. I’ve been dealing with Crew Lead Gordon Smith at Duncan Aviation FXE (Exec, Fort Lauderdale FL) during the past 15 years or so. And I always get the best service from these guys.
