igo8 satnavs

[ddtwelve]

I picked up a generic satnav with igo8 maps on it everything's great with it and I've just updated to 2013 maps ,but there's always a big but apart from the onboard route mapping I cannot seem to get a pc based route planner that the satnav will recognise.
I've got a folder igo8/content/userdata/route which is suppose to put the xml route file in but it won't work

any help please would be grateful

Why do you need to connect it to the PC? I also have a generic Chinese cheapo satnav (I think it uses NaviGo software, or summat like that). If I need something, I plot the route, then select the destination as a "Favourite" so it's saved permanantly. If I'm going for specific roads, a sheet of A5 with clear instructions in the tankbag, with the Satnav in case I REALLY foc it up.
