Summary: I bought this to replace my aging One XL. So far it has proved as excellent as expected for route planning and navigation. It is very fast to achieve a satellite fix. The big screen is easy on the eye but I can't understand why getting through the menus is so s-l-o-w. It's fast to calculate routes but sluggish to type in and select destinations, the onscreen keyboard doesn't help as you have to switch between letters and numbers when entering postcodes.
