Satellite navigation systems are perfectly legal in the UK, so long as they do not distract you while driving. That means the screen must not be in your direct line of sight and it cannot be used to watch EastEnders as you head home in the evening.
A satnav system that is properly fixed in your car, within easy line of sight without distracting you as you drive, is perfectly safe.
Many systems now also include hands-free phone calling facilities, which makes driving safer than using a mobile phone while behind the wheel. Some systems will even read out text messages that arrive for you.
One more thing - remember to keep your satellite navigation system safe when you leave the car. Take it with you or lock it in the boot, because thieves are very fond of these devices.
