Of course my only car with nav is 11 years old, maybe there are other features of more modern systems worth having. I doubt it, but I have to allow for the possibility. The real key here is the car is 11 years old - if you only buy new cars you may fail to realize how bad features such as nav age. When my car was new 3g cell networks were the fast service (4g existed but it was in the early roll out phase), and thus what I would expect my car to have: now 3g is gone - so even if my car had a NAV subscription it couldn't get OTA updates.
I'm not saying that these are inherently bad. Hell, I'd enjoy having programmable 2-driver power-adjustment settings for the driver seat. That, dual zone climate control, and google maps built into the nav are basically the only luxury features I think really add value to a car. But I'm not dying without them. Meanwhile, my wife wants all that, android auto, ventilated seats, a moonroof, the side-view mirror blind spot assistance things, automatic cruise control, an auto-dimming rearview mirror, automatic lights/brights, being able to start the car remotely, etc.
