I like mine - see post #17 above for the story of installing the backup-camera accessory with it. Only thing about it is be careful with the route avoidance settings... fee and toll avoidance is on by default and last trip it wanted to take me 1000km out of the way to avoid a $6 toll at the bridge back to Canada. In RV mode, it seems to consider nearly every bend in the road as 'Sharp turn ahead!' so I also turned off those messages. Map updates are 1.6GB so be sure you have good bandwidth or lots of time!
