## What is Garmin GPS Trainer?

The Garmin GPS Trainer simulates the system user interface and provides the opportunity to explore the features, options, and fundamental operational aspects of the avionics. When used in combination with the GPS Navigator Series Pilot’s Guide, the trainer can be an effective way to improve avionics familiarity and proficiency at a time and location convenient to the user. The Trainer is also a great way to prepare for a flight because a user can load the anticipated flight plan and “chair fly” the avionics portion of the flight before entering the aircraft. 

The GPS Trainer includes:

• Simulated multi-touch and drag interface – allows you to interact with the system, graphically edit flight plans, and much more
• Garmin SafeTaxi – allows you to view detailed airport information on the moving map
• High resolution worldwide terrain maps and aviation databases
• High resolution obstacle databases including power line alerting
• Simulated interfaces and data including:
   -- ADS-B Traffic with TargetTrend™ Relative Motion
   -- FIS-B Weather with animated NEXRAD
   -- Airspaces, airways, and Visual Reporting Points

* Note: This app contains simulated data and does not receive data from or interact with real Garmin avionics. This app should not be used for actual navigation purposes.

### 1/5 — Does not work

*2026-01-15, version 3.22.0*

Downloaded version 3.22 as I just purchased this GPS. This training app closes and will not start. Poor program for such a big company.

### 1/5 — Fails instantly at startup

*2026-01-11, version 3.22.0*

Fail instantly at startup

### 1/5 — Was great but quit working

*2025-09-27, version 3.22.0*

I used this app a lot and really liked it. Now it has suddenly quit. Won’t start.  Tried restarting my iPad mini. Tried reinstalling. Still won’t start. Now I guess I have to fly my plane to practice. Garmin should be ashamed. Guess I will buy UAvionics next time.

### 1/5 — Unusable

*2025-05-26, version 3.22.0*

The app crashes every time I click on Start. Since we can’t download the previous version it’ unusable right now…

### 1/5 — Crashes on iPad mini 4

*2025-03-21, version 3.22.0*

I have two iPad mini 4’s and desperate to practice on the simulator rather than burn Avgas, but the app crashes every time. PLEASE FIX THIS!

### 5/5 — Immense Help

*2025-01-22, version 3.22.0*

I got this so I didn’t have to waste time either on the ground or in the air trying to fiddle around and learn all the components of the 375 in my trainer. Using this for scenarios and practicing procedures has helped me save time and money during my flight training that would otherwise have been so. Great product, that has room for tweaking, but no complaints here.

### 1/5 — Not working on iPad mini

*2025-01-04, version 3.22.0*

Still not working. Update app!! Please fix. No longer working

### 1/5 — iPad Air crashes when trying to start the simulation

*2025-01-02, version 3.22.0*

Doesn’t work at all anymore! Used to work great.

### 1/5 — It would be nice if it worked

*2024-11-04, version 3.22.0*

It just blows up.

### 1/5 — App crashes

*2024-09-30, version 3.22.0*

Can’t open.  Crashes as soon as tries to open. Need fix
