Car Play is a mixed bag.
Apple Maps is not as advanced as Google, or the stock NAV for that matter.
I find that the Voice recognition is very spotty. The best way to navigate through VR on the Genesis is the Google Destinations via Blue Link. Of course that comes at a cost. The NAV system gets a much needed Voice recognition update and in my case the Map was updated to V9.5. In practice Google is best. For some POI's I had more success using the NAV VR instead of Apple/SIRI. As an example, we have a Grocery and Pharmacy chain here called MEIJER, pronounced MY-ER. The Car NAV finds it quickly. Apple could not get it right no matter how I said it. Once I punched it manually into the phone, SIRI is starting to understand, so at least Siri gets smarter with time.
I like the text integration. While you could always send or read texts via SIRI, the notification feature is nice so you will know when you get a reply.
Music is easier to navigate for my iphone using
CarPlay, but the best way is just to tell SIRI what song, artist or album you want. Again, you can do that without
CarPlay.
I don't usually do much streaming, but I was able to use I Heart Radio and some others, in addition Pandora worked fine.
Perhaps the biggest improvement with this download is the much improved VR on the car itself. I am finding POI search is much better, and the speed is also much improved. Even the basic VR for the Phone is better, but honestly SIRI is so much better that I would not use the VR on the car.
One take away.... While Ultimate owners did not get the update, most of the CP stuff is nice, but not that big a deal. I am finding that the improved mapping and VR response may actually be the biggest benefit for me. IMHO, this is where Hyundai need's to step up and show a goodwill gesture to update perhaps to V10 of the MAP software at no charge. That would show some respect for the owners that purchased the top of the line. It also is what Hyundai should do since the VR on the original software is pretty poor. My 2011 Sonata, and 2013 Azera were better.
