Particularly useful are the various other adapter plug, with which one the Navi while on holiday can load in the room in advance.
The protective bag is ideal for the Nüvi. It fits in exactly, is very well supported, yet it seems not clunky. One can still well pack in the bag when you do not want to leave in the car.
All in all, I am using the set more than satisfied and it is good value for money.
