I don't want, or need, one. Never seen the point, as I can always find my way to where I'm going etc. However, Mrs CFH has decreed that she now needs one. So, am here pleading for your tips and pointers on these infernal contraptions!
So, what's the bestest sat nav to plug in to the car then? Ease of use for set up is paramount, as is ease of understanding directions. Arrows and pointers are essential, as Mrs CFH's dyslexia sometimes means that she has trouble defining right and left, a problem exacerbated by stress (such as an annoying satnav!)
Oh, and of course, one that can be easily mounted OUTSIDE OF THE FIELD OF VISION ON THE WINDSCREEN!
