From what I've seen and read, I've got the exact same system in my wife's 2018 Kia Sorento SXL since they use the same infotainment system as Genesis and Hyundai. I've used it extensively. It's not as good as using Waze and Google through Android Auto, for my purposes.
The voice recognition is good, but not as good as through my phone with Android auto. It doesn't let me listen and respond to IM messages, only text messages. I rarely ever text, mostly use IM apps.
Do you have an iPhone? Maybe it's something with my phone that doesn't allow it to do as much as yours does with it since I'm on android. It doesn't show album art with my Galaxy S9+ or my wife's Note 8 which are two of the more popular Android phones, so I doubt it does it with most. I don't believe it works with my Pixel 2 XL either, but I haven't used it with that one in awhile.
I live in Mississippi so the traffic data is lacking. If you live in bigger, more populated areas I'm sure the built in is fine, but Waze is actually providing info based on current drivers. There's rarely ever any traffic incidents listed with the built in system, when there's multiple listed in Waze that I can actually avoid as long as I know about them. It's a nice system, but not anywhere near as good as Android Auto which is the reason that manufacturers are adding these systems in the first place.
Also, most reviews would probably rate Android Auto slightly above CarPlay as it's much more open. We've had Waze access for forever, and Apple is just now adding it. We also have a bunch of different music and podcast apps. So for you and
@Beefer it may not be worth it, especially if it's a narrow divide between how good using your phone and CarPlay is. That divide is bigger with Android though.
So, I have no problem plugging up one cord as soon as I hop in the car, thereby getting a faster charge and having a better infotainment experience, unless I'm going short distances. Of course, I'll be willing to try it again if there's an update to the system that comes with the 2020 Genesis G70.
I drive a lot, probably at about 23k miles in the last 10 months. So anything I can do to make my experience better and save time in traffic, I'm going to do lol.
