I have recently imported a R33 1993 gts-t and it has a Toyota NMDN-76004 naviken head unit in it, it is all in Japanese and unable to work out how to use it. Has anyone got one of these and know how to use it? Does anyone know whether you can change it into English, then i may be able to muck around with it and work it out. It doesnt play any cd's or dvd's either. I know there are different regions but shouldnt copied cd's be able to read still, i would assume so. The sat nav part comes with a cd for it but that doesnt seem to load up either - it comes up with all this japanese writing, the same writing that comes up when i put a dvd or music cd in it. The radio works but as japanese stations only go up to 91.0 mhz on fm, i can't get any decent radion stations in melbourne, i know the frequency crystal will need changing but should i just piss this unit off or keep it? It seems like an expensive and good unit, but should i just get a new one for it. If anyone could help me with these queries, i would really appreciate it.
