Update! MSFS2020 - Garmin GNS530 GPS Improvement Mod Pack - V.1.0.54

For those who love this old GPS I made some modifications that corrects some fs2020 bugs (especially this famous U-turn bug). Tested with the good carenado M20R.


                • - Bugfix: Fuel flow was not correct.
                • - Bugfix: Airport main runway direction was not correct for some airports.

                • - bugfix: images not displayed or flicking in nearest pages
                • - bugfix: the from/to arrow in CDI was flicking or was not displayed

                    Approach loading and activation

                    The original logic for the loading and activating an approach has been changed. This is how it works now:


                    If you choose an approach and just loading it, it’s added to the fly plan but not activated. It’s then up to the pilot to activate it or not (activate approach in procs menu).


                    If you activate the approach before the last enroute waypoint, the autopilot continue to follow the route and automaticatically activate the approach after the last enroute waypoint. If you want to bypass the next enroute waypoint, do a direct to the first waypoint approach and then activate the approach.

                    If you activate the approach after the last enroute waypoint, the autopilot goes directly to the first approach waypoint (without U-turn!!!).

                    Note: If you set a Direct To, this automatically de-activate the approach.

                    Note: If you preset an approach from the FS2020 map, this one will be automatically


                    U-turn bug

                    This FS2020 bug probably made many of us crazy. It occurs when you select/activate an approach after the last enroute waypoint. Then the autopilot comes back to the last enroute waypoint before reaching the first approach waypoint.

                    The workarround to this bug implemented here is to remove all enroute waypoints in this situation. This is not a real problem since you already flew these waypoints.

                    Activate leg

                    Activate leg now works also in approach.

                    Direct to

                    The Direct To know works correctly and you can direct to an approach icao waypoint. These lasts are available without having to manually type them in the DirectTo FPL element list.

                    A DirectTo automatically de-activate the approach if there is one.

                    A direct to an airport removes all the waypoints of the fly plan except origin and (new) destination. When doing that it’s now possible to select an approach for the new

                    destination (bug correction).

                    Remove approach

                    This fearure was not working in the original fs2020 GNS530. Now it does.

                    Graphical enhancements

                    The display screen is more readable. The fonts weight has been turned to “normal” instead of “bold”.

                    The nearest airport list doesn’t flick any more and a separation line has been added between airports for better reading. I don’t know if this works like this in the real GNS530 but I took the responsability to do it (sorry for the purists if it’s not exactly like in real life).

                    A third declutter level has been added (declutter works by clicking the CLR button while in map view). I really don’t understand how the declutter works in fs2020 but it seems that there are 3 declutter levels depending of the zoom level. Sometimes it works, sometimes not.

                    Activate approach is not selectable if not relevant (ex already activated or no approach).

                    1. Love this mod! Any chance of adding an OBS & SUSP function in future? Very essential tool for sector entries and VOR/NDB intercepts / NPA's.

                    2. So I have to say I love the mod too. Just one problem I am having and I cannot figure it out to save my life. I first downloaded the new mod and unzipped it in my community folder and it worked great. This was on my set up at my house .
                      So the next day I go to work and I do the same exact thing. Step by step on my set up at work, and nothing:-(. I have taken everything out of my community folder (was not that much to begin with). I unplugged everything and did everything to troubleshoot. Does anyone have any ideas ?
