Regarding the parking sensors, I'll be interested to see if they only make a noise or also provide a good graphical display showing the distance remaining to the obstacle. The sensors on my HR-V are too coarse and give a continuous noise when there's still a significant gap to the obstacle (I presume the Jazz is the same).
And a key question has to be whether the "OK" button on the infotainment screen has been banished.
The Jazz handbook says that the rear centre parking sensor sounds continuously at 35 cms or less, and I think that's about what mine does. There's no front centre sensor, although I don't know why - I would welcome one.
I think the OK button or some similar warning may be a regulatory requirement, or a device to protect the manufacturer from injury claims.
