Safespeed is a £6 per month add-on to the professionally fitted Smartnav navigation system, which automatically updates every time you download a route.
However, it doesn't register mobile sites, and if you don't have the optional £200 touch-screen, there's no indication of speed limit - although there are different volume levels if you're exceeding it.
It's great value if you already have the sat-nav system, or can justify buying it.
