Tomtom GO

Call it stupidity, call it impulse buying, but once I saw this thing I had to get one. It's a great car sat-nav system that's really easy to use and doesn't need any professional installation!
Real plug-and-play if you ask me. So, what does it do? well it's supplied with a map of great britain, including all major Points of Interest (eg cash machines, restaurants, parking, repair, hospitals, theme parks and tons more). You can either tell it to take you from A to B, or even better ask it to find the closest point of interest and it'll show you how to navigate there. It has a real-time 3D interactive map and gives clear voice and visual instructions on what to do next (in a sexy voice nontheless).
All in all, a great product that all drivers must have!
