In other news, just bought a Xanavi 2005 2006 update set.
according to the guys I spoke to in japan, CD-ROM B contains a firmware image, so gonna try decompiling it to see what I can meddle with. Hopefully should mean I can have my own custom boot screen and language. Also itching to plug my bus probe into the factory stereo to see if I can replicate the signals going to the info screen, like they've done with the RX-8. mock up an ipod adapter using an arudino and plug it into one of the data feeds, to show song name etc. or at least get it to work with the remote on the steering wheel using an aux mode on the stereo.
These new age bus electronics are fun to hack haven't been this excited since hijacking the bus on my golf.
