I personally don't think so, the quality of graphics isn't that great I haven't found the maps or traffic to be any better than the two I use (sygic and Apple Maps). I also have the dash display so I can get the map on that so that's another nail in the head of ACP. As far as audio playing goes I can't see much between them they both have the same annoyances, such as when I select an album from an artist they play that one album and stop my XF used to play the next available track and continue on from there useful if the music is there for background.
I didn't pay for the update as all hardware was in place and it came with 18D, I believe that the usb interface on some cars need changing to add ACP/AA but not sure why as the interface is the same for incontrol apps.
The other negative is it needs the cable connected to the phone and I can never be bothered to connect it unless the phone needs charging and then my High speed charger charges a lot better.
