The top two trims of the new Glanza/Baleno comes with a hand rest center console. Apart from being a handrest which is mighty convenient the console has a small box under the hand rest and there is also a rear AC vent for the rear passengers. The two lower variants does not get this convenience.
Installing the handrest is pretty straight forward and easy, but the AC vent will be just for show and it will not work. So to install handrest with a full working rear AC vent you will need the following parts. This is not a DIY and you will need the help of an AC technician since dashboard has to come off partially and needs a lot of patience. The complete installation (except the rear cover of the handrest console with the power adapter) was done by the AC tech and he did a good job there are no rattles or other noises.

If you need the USB and USB C charger combo you will need this part too, 39470M55T00. I wanted to install this at first but then decided against it since I did not want to do further mods for the time being. So The original charger along with its warning sticker was glued and screwed on to the new rear cover.
