Sometimes you can not read the content well but we can help you from the same application on the phone. I briefly explain how I did it. More ahead I will go up explaining videos.
We will need to have a phone with Android.
First, we installed the app on the phone and in the watch (via apkinstaller). The application (apk) that I have installed is called "All-In-One Offline Maps + .ver.2.4.build.51" if you put it like that in google you will appear to download.
Then we open the app on your mobile phone:
• We go to the symbol of the map,
• Click on "save an area"
• Framing the part of the map that we want to save and the zoom that we want to obtain
• Press the save button
• This process will take a long time to download
• Once downloaded we will go to the root folder of the phone and copy the folder "OfflineMaps" and save it in our PC.
Once the folder is saved in our PC we replace it with the one in our amazfit . Now we will open the app on our amazfit and should see the downloaded area. It perfectly locates our location. To be able to know what you put in the options it is better to go browsing the app on the mobile at the same time.
Sorry i can put a link because i am a new user.
Search: "Amazfit Maps + GPS offline [NEW APK compatible]" in youtube and you can see a video demostration
I hope I have been helpful.
