I had a NBT Evo retrofitted this weekend, to replace my CIC nav. Probably one of the best mods for a pre-LCI car in my opinion.
Aside from how modern the NBT Evo menus look, compared to the CIC, the voice control on the NBT is simply amazing. Gone is the old "tree" like structure of the CIC (i.e. on the CIC you can't just say "call John", you have to say Phonebook first and then say the name). I feel like I can almost converse with the NBT and it will understand me
The ceramic touch controller with write function is cool, but I find myself using voice input most of the time.
Carplay is also nice, although I'm not sure how often I'm going to be using it.
The nav on the NBT is also much better and with the NBT you're now getting nav queues on the head up display as well.
Overall, I'm pretty happy with the upgrade. Some pics of the new looks:
