Does anyone know where I can get software for my navigation to be in Korean language instead of English?

 

I had a funny, albeit smart-alecky, answer, but you're brand new here and I don't want you to feel offended.

So my real answer is you are probably going to be out of luck. It surely exists for cars sold in ROK, but since the nav system is downloaded by computer rather than DVD, its not likely any dealer here can get it.

I would contact Lexus directly and see what they can do.
