Yes, this. The only reason I use my car stereo's built in GPS system instead of Waze is I don't want to futz around with my cellphone while I'm driving. My car stereo's GPS is tied in to the traffic info sent via Sirius/XM satellite radio so it's smart enough to re-route me if traffic jams are reported. If my stereo had CarPlay though, I'd expect Waze to work through it.
Make this available on CarPlay
