None of the above choices .Because the display is small and unobtrusive .Because the user could understand the information being given by the device .Because the suction cup falls off sometimes .
Why was the loud speaker able to overcome the problem with the display ?
The mounting hardware for the TomTom leaves something to be desired , as the suction cup has fallen off a few times and the power cable plugs into the bottom of the unit , which can interfere with the dashboard if you do n't place it high enough . Occasionally we had difficulty reading the next turn information on the display , as it is somewhat small and unobtrusive . The speaker , however , was loud enough to overcome this problem most of the time , even with our windows down .
