My Crosstar comes with all of those features, except the Blind Spot Monitoring. But Jazz Advance should also have that one, an orange light that is shown on the side mirrors when a car is in your blind spot. So Advance should have all of those features.
The door mirrors fold in/out automatically whenever you lock or unlock the car. This can be also turned off in the settings, which I did in the winter when the mirrors were so frozen that they couldn't fold in or out by themselves.
Front seats have 3 heating settings, and it automatically lowers the setting from 3 to 2 after some time, and I think even to 1 if you wait long enough. Steering wheel heating is turned on from a button on the steering wheel and it turns itself off whenever you turn off the car, and you have to remember to turn it on again next time you drive, if you want to use it.
Reversing camera turns on whenever you put the gear selector to R, and that is the only way to turn it on, there is no other button for it. It has a quite wide viewing angle, which is nice when reversing out of a parking spot between other cars.
The keyless entry requires you to have the key somewhere near front doors, or near the rear hatch, for example in your pocket, and then you can lock and unlock the doors by touching a certain spot on the door handle, or a button on the rear hatch. This is nice as you don't need to take the key out of your pocket. I wish that it would also automatically lock the doors when you walk away from the car, but unfortunately Jazz doesn't do that, and you have to remember to touch the door handle to lock it.
