The F20, provides you with a lot for very little. Loaded with features normally found in other, more expensive car navigators, the F20 packs them all into a neat, pocket-sized compact unit. It?s the advanced features that separate the F20 from other entry-level navigators. The ?Nearest Parking and Petrol? buttons, previously only found on our more expensive models, are a simple but brilliant idea, exclusive to Navman.
