hello i just bought the 2018 model Fit, and it has VXF194 VFI radio. its imported from Japan and I'm glad that I can change the language but my friends cant change language because they have 175 or 155 models , is there any way to access the secret menu in this radio to change settings? I'm interested to turn off GPS because I cant change clock in car and only way to change clock and access menu in to cut wires and make connection without GPS , if there is any other way ? please let me know ^^ I turned off car and pressed menu GPS and - buttons when I turned on the car navi update menu comes on but I cant do anything from there and I would like 2 thing to do update the system of radio if its possible and change the clock and map so I guess its 3 thing XD I also have sd card and gain access to write the data and read the data but Idk which PC program I can use to download and update system :/
