I strongly recommend Navigator. The software is only £49.99 for the whole of Europe including GB & Ireland and Switzerland. Maps are from TeleAtlas so are as good (or bad) as anyone elses. Voice directions, map rotation and auto recalc if you go off-route.
I've seen the new version and it's looking superb. Bigger icons, better junction diagrams. Maps look much nicer with more detail including house numbers, routing and re-routing is improved. Cross countries routing is now available. Routes can be planned ahead and saved. In fact just about everything I've ever been asked for!
