Thread: Garmin Hydra

OK I tested this now on a ASUS 8" Tablet Android 6 and all the menus are OK.

File layout is the same for most Garmin units.

After you install the app the Garmin folder is made. (you do not have to make one)
Just start any of the apps and the folder is made.
Any map img files you put in goes under the Garmin folder.
Be it gmapprom.img , gmapsupp.img names.
Note if you are using any official Garmin's maps you will need the unlock key file also.
Be it gmapprom.unl or gmapsupp.unl
They go in the Garmin folder too.

Open street maps do not need a unlock key file.

Then you add a GPX folder under the Garmin folder for any tracks you have or Geocaches.

You will need to start those apps so the files show up on the map you use.
