The Navigon 5100 is a bit of a mixed bag. It does some things well, like motorway driving instructions, has a really solid windscreen mount, a system that's about as configurable as you could hope for and one that's pretty easy to use. There's plenty in its armoury that should make it a PDA or smartphone navigation-beater. However, its urban navigation is flawed, address entry is fiddly, the maps are a not as clear as I'd have liked and it's not the best value for money.
