Are you familiar with igo software?

Hey there...
A friend of mine asked me for a favor and I may have ducked up bad here...
OK, I went into the tablet settings, went into storage and cleaned all misc files.
It turned out there were some software components or maps or whatever, that were required for the igo GPS software to work properly. Now when I start the icon all it says is "insert the igo SD card".
Does the SD card contains the maps, because if that's the case I will try and download them from somewhere. I already found a couple links...
She said they have installed some program to be able to install the igo software... But the software is still here. I don't even know what's missing.
So can someone help me out here? Otherwise I may have to buy her a new software...
