Ive got a 4 month old V40 R-design Nav... and tbh the sat nav is rubbish.. My old Megane had an inbuilt TomTom.. that was fantastic..
Im constantly driving up and down the country so I wanted a nav inbuilt in my new car.. save the hassle of setting up taking down keeping safe.. not much bet when u do it everyday its just easier..
Now I find my self constantly checking google to double check the route.. Tonight for example google was 20 minutes quicker on my 2 hour journey compared to the quickest route on my Volvo Nav..
But other than that.. I love everything else
but wouldn't recommend the nav
