The main upgrade is that this model has a lifetime subscription to an HD radio traffic and news service, as well as sports scores. Also, the KW-NT50HD has dual tuners, making it possible to simultaneously receive traffic data and listen to standard HD radio. Also, these news and info features work via a paired phone's data connection if the user is outside an HD radio area. The map base is powered by Google Maps, and the unit uses Windows Automotive OS, and there is also Bluetooth connectivity allowing hands-free phone use through the car's main speakers. The radio feature can tag songs for downloading in iTunes. There are many navigation features, including text-to-speech and voice guidance in English, French and Spanish, points of interest, visited destinations, speed limit and speed alert displays. The display itself is a relatively large touchscreen (6.1"), and features a removable faceplate to discourage theft. A proprietary iPhone app turns the iPhone into a sort of remote control for the player. This model has a $200 price increase over the one with no subscription.
