you have probably read how the guidance be not perfect and I be not go to tell you otherwise . but any time I have find myself get mislead I just use the map and regular map reading skill to start move in the right direction . the device will recalculate and you be on you way . with the clear , concise voice direction you can still concentrate on avoid other car . so what if I miss a junction\/turning - I just keep follow the purple line ! and yes - when you take it on the plane it can be a little slow to get it be bearing . but the 15 minute ride in the rental car shuttle be usually enough for it to figure out where it be . slap it on the windshield and you be ready to go when the barrier go up . finally , the interface be just how it should be - the button logic be clear and operation be exactly as you would expect . no complaint apart from the occasional minor route error . when I use map print out there be many more error and a lot more stress ...
