Car computer systems gather data about how you drive, speed, braking, location etc and then there’s all of the voice control info and Bluetooth that has your phone contacts and GPS that retains every place you’ve been etc.
2006 not so bad. I have a 2008 F250 which is nothing fancy. I’d say it’s the Windows XP version when compared to the new models.
There is no bluetooth in the car it does have a fallow vestigial onstar.
