I have to agree to a point. My '18 came with it and I guess it's nice to have but it's soooooo slow. Yeah, when I'm out running errands, I just set the phone down on the pad between stops and it gets a little charge which is nice but nothing that is noticeable really. For longer trips, you will get a decent charge but I agree that at that point, you might as well just plug it in. I only use Android Auto on longer trips so again, the wireless pad isn't really used then.
I guess my point to others trying to add wireless charging is, depending on the cost, it might not really be worth it. Maybe find a nice phone mount with integrated charger or something like that. If you just want a cool mod, go for it. Just don't expect charging miracles out of it.
Now, if someone can integrate a fast wireless charger, that would definitely be worth the investment to add this to a truck that didn't have it. I'd also be interested in adding a a second charging pad for the wife but I don't know where I'd even put it. Maybe in the upper glove box?
