Just installed the software for my gps for the tomtom program. No problems at all regarding software installation, however i ran into the same problems as dj when i just went for a little drive. The screen kept freezing and was rectified by tapping in and out as dj suggested. Other little things i noticed is i actually liked the igo gps as it finished off my suggestions. eg, if i pressed M, E and then L for example, melbourne would come up. Really useful when your in a rush. Only needed to type in a few letters and bam it comes up. One thing i also liked about the igo8 gps for example was this; say for example i entered deer park as my suburb. And ballarat road as my street. Ballarat road runs through about 10 different suburbs ranging from house numbers from 1-only god knows what. One thing that i liked is if the house number didnt correspond with the suburb the street ran through, then it wouldnt register. Not sure if this was applicable with the tomtom program however. PERSONALLY, i like the set up of the igo better than the tomtom. maybe i havent warmed up to it as of it, but because of that problem me and dj encountered i just put back my old igo gps. too bad the updated igo gps links above has very very very slowl download speeds :(
