I haven't had time to take screenshots or do a proper review. I've used it several times now including a day trip to France and navigating in the UK. A few quick pros/cons

Pros
- stable so far
- fantastic screen, but we knew that :-)
- ease of installation/setup
- finger operation
- speed camera warnings, very easy to install/update with a wireless internet connection
- sturdy holder for 770, seems very secure when attached to windscreen/windshield
- recalculation of route seems very quick if you take a wrong turn
- europe wide maps


Cons
- at a roundabout you get advance instruction e.g. "at the roundabout take the third exit" and then when at the exit you get the instruction "take the exit" - the second instruction is just a little late
- can't do cross border routes, not a big issue for me but could be for others
- the maps are no substitute for local knowledge and do have ocassional errors for example one of my local roads is buses only but it tries to route me down it
- if all you want is sat nav there are plenty of cheaper solutions
- they should supply more than one piece of velcro for the gps device so it can easily be moved to another car
