First off their system takes an eternity to cold boot. If I’m making a quick run to the store or dropping the kids off at a friends house the system isn’t available for most of the ride. While it’s booting, the radio remembers what it last did but all the controls including volume are locked. So if I was listening to one of the comedy channels on Sirius I have no way to mute it or turn down the volume of the often inappropriate content for a few minutes if my kids get in the car.
Second the system remembers very little of the settings between drives. For example the heated/ vented seats or the auto-hold braking feature have to be set every drive.
I just drove a brand new Ford Fusion rental this week and their system while much clunkier did boot up almost immediately upon starting the car. Of course nothings perfect and while Ford did include hard buttons for most of the HVAC controls you still had to go though the touchscreen menus to find the setting to change the vent control to head and feet.
