Update! MSFS2020 - Garmin GNS530 GPS Improvement Mod - V.1.0.7

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.

V 1.0.7

The CDI look and behavior conform to the original

Added a BRG mark to the default NAV page compass

Added a terrain map NAV page

Always one decimal on DIS and XTK displays

Radio part look conform to the original

Changed colors

Bug correction: activate approach not always working

Bug correction: FPL leg updated after activating approach

Some minor corrections

V 1.0.6

First declutter level hides roads and airspaces

DME distance correctly rounded

LOC Radial not any more displayed as in the original GNS530. LOC name displayed instead (ex ILS RW 31).

Adding compass in track up map mode

Default NAV page is in track up mode by default

Adding range levels to 2000nm

Prevent changing the TRK field (like original GNS530) in default NAV

Better management of the CLR button in NAV pages

Map page completely rebuilt

Frequency NAV page works now nearly like original GNS530

Flight plan has now 7 lines instead of 4 (5 vs 4 in GNS430)

Depart and destination now displayed in flight plan

Flight plan columns conform to the original GNS530 (added DTK and changed order)

V 1.0.5

Fixing the conflict when using 2 or more GPS in an aircraft

Works now with Cessna 172

Some small enhancements and bug corrections

Modified GNS430 now included

Adding TRK indicator

V 1.0.4

Big mistake in v1.0.03 with track up half working

The DirectTo behavior is now nearly similar to that of the native GNS530

Adding toggle of map orientation in map menu (North up or Track up)

Better management of the CLR button when inserting a waypoint

Prevent add/removing of waypoints in approach sequence (for now)

Bug correction: crash in load approach page when loading and there is no approach available

Adding confirmation window when removing approach, SID, STAR or waypoint

Removing approach, SID and STAR works by selecting the corresponding line on flight plan

Less dependency from other Mods

V 1.0.2

LOC/VOR correctly displayed in the VOR field following the captured frequency

Setting 4 levels of declutter as the original GNS530

Adding the range and declutter level in the NAV map (left bottom corner)

Adding missing symbol files associated to waypoint, airports, etc...

No more flicking pages (I hope)

The NAV/COM page now works

V 1.0.1

World4Fly Mod integration (Wrong radial and Rounded DME)

NAV page now displays ETE to next waypoint instead of ETE to destination

First release features:

Better logic for approach loading and activation

Correcting the crazy U-turn bug

Activate leg now works on approach waypoints

Better DirectTo management and possibility to Direct to an approach icao waypoint

Bug correction when direct to an airport: it was then impossible to select an approach

Remove approach is now working

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

Display screen more readable

Airport list: Correcting flicking bug and enhancing the view

Adding a declutter level

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).
