I love my Mio Spirit LM 697 Truck and mostly it impresses me with its reliability and the way it keeps its GPS signal even in difficult situations. One thing bother me is how good is the Truck mode I tow a caravan and one of the attractions of the 697Truck is the Truck Mode which I hope will stop me taking my outfit down lanes not fit for caravans or trucks. However it has on many occasions suggested routes which I have ignored as in my opinion the road width is not sufficient for two vehicle to pass or the route just looks doggy. I am beginning to think that the fastest route is the same for car, truck or caravan and that Truck Mode is just kidding. What do you think?
