I bought this for the new Tomtom Go 5000, and it's a snug fit but it's better than being loose. Recommend if you want a soft case to keep the device in great condition. There is a front pouch for the cables too.
For less than a fiver, it represents excellent value for money. Fits really well, has a great feel. Yes is doesn't protect the front, but no iPhone cases I've ever purchased have and thats what I like about it. All the buttons are visible on this and it protects the sides and back - what more do you want for a fiver!
