These buttons on the left would only work with the Gather's system, which comes as an option. One is for displaying Gather's menu and the other is for multiple display. I downloaded the latest manual and showed it to a Japanese friend of mine and also confirmed from few friends in Japan, these new models time segment is connected with the GPS, through Gather's system. So no time adjustment through regular menu. I am in contact with a local vendor in Karachi who gets the android systems made through a Chinese firm. They have asked me send the pictures of all the empty jacks in the center console and they would try to find a way to power the company installed GPS. Till then nothing
