GS340 lexus stereo in Japanese

Would love to know if anyone could help me out understanding my Lexus gs349 - imported from Japan to New Zealand and the stereo is in Japanese. I can work out basics but I want to pair my iPhone to car and be able to answer calls and play music through stereo - must be able to do this but don't understand anything coming up on tha screen. Would anyone be able to help?

for a start, make and model of the car stereo would be helpful.

and the perhaps a picture or two of the stereo screen?

the stereo system that came with your car may or may not be original stock.

just post those info and we'll see how it goes...
