Just this week someone was killed because an owner of a 23 expy reversed into a strip mall. Dnt know if it's shifter related. I had a couple hiccups with mine, but I liked it mostly. I much prefer lincolns button solution though, barely any hiccups, easy to use, and u always know what gate ur in. And it's not annoying like other button shifters either.
I saw someone talk about the reach to hit the button. Yea there's a reach, but if your sitting up because you just sat down, it's not an annoyance. It's only an issue if you were already sitting and need to put it in gear. Mu wife has never complained, she loves the nav so much, she's the reason I still have it.
