I was fortunate (foolish?) enough to buy a new car this year (Octavia VRS) and I bloody love Apple Car Play! I have all my music on my iPhone so to have seamless, responsive access to that library with the IOS interface along with the ability to use Spotify and Maps through the in-car system is great and both the in-car voice control and Siri work really well, i.e "Play album X" or "Show me how to get to place Y"
So yes - would highly recommend a head unit with this functionality (as well as the Android equivalent depending on your preference)
