2018 Man TGM Radio MMT unit and USB not working

Hi. Im new in forum. I just started to drive with 18 plate Man TGM. But radio MMT unit and usb socket are not working. Anyone knows where that fuse can be. Probably thats first that needs to get checked but dont know where. Looked under the dash in passenger side fuse block but no luck if its even there. Cigarette lighter socket works. Any idea? I was on it 2 days and drove in silence…horrible. It was defected by previous driver but who knows when company will sort it. I need my work phone get connected to it to use handsfree . Thank you
