One of my colleagues has an app for his Ipod Touch that he now uses instead of his very expensive (and useless satnav). It costs about £70 I think and her really recommends it. I use an RAC satnav in my role and find it's fine and I also drive all over the country, but I'm not sure about foreign coverage. This is my 3rd satnav and it's the best one I've had so far.
