I don't want to have a separate TYP file and a IMG file to upload.
TYP file is subfile for uploaded IMG file. It is not work as separate file! The customs polygon section do not allow to use not-standard Garmin texture, but TYP section in uploaded IMG give you this possibility. Garmin always use TYP too and you no need to worry it is official Garmin tool!
