these buttons r related to the navigation system (which can be used in japan only):d........... press the button in first pic and speak out the address where you want to visit in the microphone in 2nd pic. and then the navigation will start guiding you......... this is v convenient and safe. while driving u dont need to touch the navi screen and all that stuff....... just read-out (K) the address in micriphone (Y)
