The 2014 Pioneer models have a feature... not yet implemented... that will allow on the fly map data upgrading. It requires access to the internet, either via wireless hot spots or tethering from a smartphone. Since I sent over a grand to Pioneer for the 2013 flagship unit last year, I'm not willing to do so again this year.
All of the 2014 Pioneer head units will be Carplay ready when they release the firmware for it, supposedly later this year.
