### 3/5 — Limited Usefulness

*2025-02-01, version 6.73.1*

Okay for practicing how to move to around to different pages & learning where information can be found, but has several limitations. For example, VNAV function does not work (will not descend using altitude constraints in flight plan, even in the flight plan + vertical mode). Does not have even a very basic autopilot controller like the GNS trainer had. It would be awesome if it had the GFC 500 AP integrated and if VNAV worked.

### 3/5 — 650 trainer app

*2025-01-19, version 6.73.1*

After putting in a flight plan the airplane starts out on the other side of the country…can’t get it to start where t.he flight plan is.

### 1/5 — GTN750XI use to work till latest upgrade

*2024-11-12, version 6.73.1*

GTN750 app works and loads GTN 750XI app crashes when start button is pushed and takes me back to my IPAD home screen. IPAD mini 4 software 15.8.3. To bad an option is not available to roll back to the version before this that worked for me. Even on the Garmin product line you do not know what damage or functionality is lost with software updates.

### 5/5 — 650 Trainer shuts off

*2024-08-25, version 6.73.0*

Gtn 650 closes out and stops when going to find frequency, recent.

### 1/5 — Does Not Work

*2024-07-29, version 6.72.0*

I’ve attempted to download and redownload the app several times to no dismay once the app starts it’s able to show the GPS but only with a blank black screen on display

### 4/5 — Great training tool

*2024-06-20, version 6.72.0*

I used for my primary training and now for my students. Great tool. Having trouble with app lately though. 750 screen is black on startup and won’t turn on? 650 just get a spinning circle. Hope Garmin gets this resolved.

### 1/5 — Useless

*2024-06-17, version 6.72.0*

Started it up and nothing comes on the screen, useless.

### 1/5 — Loads but will not turn on.

*2024-06-03, version 6.72.0*

This app is useless.  It loads up, but the device will not turn on in the app.  I have deleted the app a few times and re-downloaded the app with no change.

### 1/5 — Won’t turn on

*2024-06-02, version 6.72.0*

There is no button or toggle to turn on the app.  The GTN unit looks real nice but it’s inoperable as no button or setting will make it come on. I tried every different settings option available.
