Do anyone have any idea how to add more language to the Z1? Since the Z1 only display English, French and Spanish.

I highly doubt you can add more languages. We have been working on accessing the hard drive for things and that's being a real pain. Adding BMP's for images and possibly adding music (if we have a converter app written) might be possible. But adding a new language, I would doubt that will ever happen.

send pioneer an email, when they receive a few request they'll think about updating that issue in future update.
