I am looking to buy a 2017 NX Turbo. I like the base model as I don't think the Nav is going to be useful (gets poor reviews like most car Nava) and I use the Waze app on my phone for any Navigation. I do want to make sure the car is equipped for options down the road where I could possibly display waze or the iPhone map on my screen. Does anyone know if I would have to have the model with the Nav screen so it could display that or does the base model screen run apps? Any insight on running apps on the car is appreciated.Also, do all models read texts out loud? And can you recite texts back?thanks!
