Sorry maybe I didn't word that very well, big screen but no satnav - wasn't expecting the screen! This opens a whole can of worms whether you can retro fit a satnav system!
In regards to the graphics, they look pretty good and the touchscreen is pretty responsive! It's decluttered the centre console massively!
I think it's half a second quicker on paper, haven't had chance to plug in my OBD reader yet!
