Hi Alex,
Its great to see the discussion. I have AVIC RZ06 installed with Japanese language. As per your instructions, I backed up the FW files which I am sharing here. Please have a look. It also named as AVICRZ09 in the NAVIUP folder after FW backup. NAVIVUP AVIC RZ06.7zI have no programming background. Just a thought, is it possible to replace the PS140PLT file with yours of AVIC RZ-09 for language change. Many thanks.
