When I got it to work last, (which was a pain in the butt to install) it worked great. The issue here like you said is the garmin trainer. Look, I am not trying to be a jerk, but let me give you some background on me first. I don't need your product, I can use the native gps just fine. But I own a virtual airline, and I provide a lot of support for my guys when it comes to add-on software. Also to be fare, I have had issues of the same sort with Flight One's GTN for P3D in the past. I own every simulator there is, and most of the add-on software as well. Recently I wipe my hard drive and started fresh. I was debating on even installing the GTN because I hardly if ever use it, but I thought I would reinstall it and make a video for our guys to show them all the features. My back ground is pretty stout when it comes to computers and flight sims. I right a lot of my own add-ons and tweak aircraft and lua files for X Plane 10. The point is, if I am having to trouble every time I install your product, which every time I have installed your product, I have wound up in the forums; imagine what the newbs are going through. You guys need to get the issues fixed, and frankly getting away from the flight one method of delivery and installation, particularly for X Plane, would be a good first step.
