Will I be able to read the screen?
Each satellite navigation system has its own features, but most now have screens where you can alter the brightness of the display to suit conditions.

You can also mark specific spots and store them in the satnav's memory, so you need never miss the turning for Great Aunt Agatha's country cottage ever again. These are called points of interest or POIs.
Some critics have started to moan about how safe satnav systems are to use. They see them as a distraction that can cause accidents. It is true you should always pay attention to the road - and never try to program the thing while you're on the move.
