I'm just trying to cope with it.
The question was indeed to load maps on the SD card and that still stands.
Because It didn't work I copied IGO also to the SD card.
The point is how can I direct IGO to look elsewhere than it's directory in the device itself?
Now I have two times IGO with maps.
Some mistakes where suggested like how to adress the SD.root.
For instance.
As someone correctly posted it should read:
[folders]
content="\SDMMC\Content"
And yes there is an OZ folder on the device whether you believe it or not.

And Boki Srb I don't like your attitude in this, although I appreciate some hints.
I try to follow, but it's not that easy. So it's not that I won't listen to others as you concluded.
I've been a computerengineer, but that doesn't make me an expert on GPS devices, especially not on it's software.
There are more commands and rules IGO won't follow if it isn't done exactly right.

The possibilities of SYS.txt alone could be a very long list.
