Brief History: Purchased GRT Sport 1 yr ago. Have had a problem with the unit booting up. When power is applied, the backlight screen will flash then go blank with nothing to follow. Other times, the GRT logo appears as it should and the "accept " page follows with normal function. The unit has been back to GRT twice. The processor was replaced the first time and the processor again along with the main board the second. The unit was placed back in the plane two weeks ago and seemed to act "differently" on initial start up but functioned fine until today when it wouldn't boot up at all until after the flight when it decided to work normally.
I love the guys at GRT but I'm getting frustrated. They've been telling me for six months that they've had this problem with occasional units and they're working on a graphics driver patch. In the meantime, this EFIS is totally unreliable and I have to believe others have had similar problems. Any thoughts before I call them tomorrow and lose my cool. Thanks.
