Quatix 3 tide and weather doesn't work in Brazil

I just got a new Quatix 3
To my surprise, this two things , that makes the biggest difference between the Fenix 3 and Quatix 3 from , don't work.
Weather and tide.
Later checking the garmin forum , I found more customers complaining about it.
It doesn't work at all in north of Brazil

So I think that garmin could develop a way to have it fixed.
Maybe letting us to put the coordinates ( latitude and longitude) when we don't have a tide station available nearby.
