4.5 Easy to use! DiamondsAreForever | 06/05/2009 | See all DiamondsAreForever's reviews (459) This was my very first sat nav, and I'm so pleased! Its extremely easy to use, clear daytime maps, night vision maps, clear sound, you can choose between a male and female voice, the screen is just the right size... I could go on forever. There is also a great HELP option incase you ever breakdown, with first aid tips and everything. Its easy to navigate local facilities, everything from places to eat to tourist attractions. I also love the fact that when you are approaching a roundabout, it gives you plenty of time to change lanes if you need to, by telling you early. Its the ultimate sat nav out there at the moment!
