Just bought the CX-5 GT with tech package and it is fantastic. Blind spot indicators work well, adaptive cruise control is nice for highway driving, and the headlights are superb (they also turn to follow you when your turning the car...) - also like the auto sensing windshield wipers. Nav system is nice, but doesn't take traffic into consideration like Waze does, so I don't use it much.
Overall love the music system --reconnects my iPhone every time I enter the car and starts my music back up (whether it's Apple Music or another music app).
I didn't get the bumper sensors (optional, can be added by the dealer later), but the backup camera projected graphics let me know how close I am to other objects/walls when backing out of or into a parking space.
Autowipers and blind spot sensors aren't tech package items. Or, at least they weren't in 2014. I actually find the autowipers to be a bit annoying, especially at night. They don't work that well.
