Sat Nav View Quest widescreen with UK Maps This is a GPS with a difference. The first thing you notice as you unpack the box is how slim this View Quest GPS is. At under 12mm thin, it's certainly the most portable sat-nav on the market. But the GUIDE4300UK isn't all about the looks. The powerful 500MHz processor and high sensitivity GPS receiver mean you will be on the road and driving quicker than ever. As well as the basic features such as POI support, day/night modes and 2D/3D views, the GUIDE4300UK benefits from some great additions such as GPS data logging to keep track of your business mileage, and it even continues navigating while in a tunnel!
