How do I move the iGO8 onto a bigger micro sd card. 2GB just is not big enough, i have a 16GB card in my phone with about 5 free and would like to get the SW onto this card.

Is it possible?

Unlike TomTom and some other nav programs, iGO does not influence the system files, like windows registry. So you can copy/paste or move the files easily.
Only thing you must keep an eye on is the path you use to start iGO.
