I have a go 730 v8.000 & map v8.0017.27. I don't want to upgrade the go730 maps and apps because they took away features that I needed. Unfortunately, I just updated my TomTom home app and now I cannot "operate my go" from my computer. I don't know what my original TomTom Home version was, but does anyone know where I can download earlier versions. I must say that I've never owned a piece of equipment that was degraded like my go has been with upgrades. I realize that the upgrades have "fixed" stuttering etc for some people, but for me they've been a royal pita.
