Hi Brett. I now find myself in the same situation as you. I have the Legacy 2.5GT Spec.B imported from Japan into NZ. My car has the Kenwood Navigation / stereo system. See photo attached.
Like you, most of the radio, DVD, Bluetooth functions I can work out.
But I just can't navigate through the Japanese display to work out how to set the clock / time and I'd love to be able to setup my hands free properly.
Did you find a solution?
Ether way I'd like to here from you as I'm determined to work this out. Even if I have to translate the Japanese manual... which I have. Perhaps we can help each other out.
Has anyone else found a resolution?
