I just purchased the Gtn750 and installed it. The Garmin Trainer works fine, but the 750 shows a black screen. I installed it into an AFM Mooney Ovation II that was already set up for the 750.
When I was installing, I got an error message "could not move file rxpGtnSim32.dll. I tried various times and thinking it might have had a problem with my antivirus program, I turned that off and tried again. The file error still happened. I typed Ignore and went on with the installation, but of course I get a black screen. Could you send me that file and I'll drop it into it's place?
Thanks...
