39 of respondents said that they’d rather use the navigation app on their smartphone than the system built into their dashboards. (That’s less than half of the study participants, obviously, but it’s also up 19 percent from 2014.)
57 percent of respondents wished that automakers would stop trying to develop their own infotainment systems (looking at you, Toyota) and focus their energies on making it easier to sync smartphones with third-party providers like Apple (CarPlay) or Google (Android Auto).
