Archiv / Down Igo8.3 on Unlocked Navman?

Hello i have recently unlocked a Navman S30 and whant to put a igo83 with ner maps on it.

But i dont now really where to put the igo8.3 map?

When i put the igo8 map on the INTERNAL memory of mine navman N20

like this:

\Programfiles\Igo8.3

Then i can use the FileManCe to go to \Programfiles\Igo8.3 and start the igo.
But the problem is that i want the igo8.3 on a SD card, not internal memory, becouse the igo8.3 maps are larg.
and when i put the files in the SD card i cant open them :/

How can i fix it? How can i make so everytime i start the Navman that igo gonna start automaticly direkt from SD card?

thanks
