I dunno, I think the HK system works just fine on my RGS. Aside from having to add an aftermarket amp and speakers to make it easily listenable at road speeds, its biggest problem is sun glare in morning and evening, but that is not HKs fault. This biggest problem with CarPlay on a ->touring<- bike is that, one way or the other, you are beholden to a cell connection to make it work. Whether it is updating maps while riding or trying to download maps at the campsite with spotty cell reception they are basically internet appliances. The built in HK system will update maps whether in town, in the sticks, in the canyons, or under tree cover. Cell phones are nice, but I would not call them the worlds best for touring. A sat phone, perhaps, but not a cell phone. And let's not even get into Waze and other apps mailing home your get away locations to the data miners of the world. I don't care, but more libertarian minded folks might.
Distraction issues aside (really, we WANT riders to look at their dash more?) it seems CarPlay is really more for round town riders and commuters more than touring folks. Which makes it somewhat odd on a GW, IMHO.
