Thanks all - interesting that the open source one is so much more detailed! Sounds like I have some thinking to do regarding 800 and 810. And then there are the touring options too (which I've heard really mixed things about). @Thuekr the 510 uses breadcrumb navigation, no? So you don't see a route as such, just follow a line of dots?
The 510 gives you line on your screen, the name of the road, an icon showing you the next turn, audible sound when you are approaching the turn - and breadcrumbs from your position if you should deviate from the route :)
