hi, can we arrange circle button up right and down ways. for ex: when i press circle button right, it jumps next song. i want that, when i press circle up, it may jump next folder. is it possible. like that: when i press right in radio, it continues 0,5mhz. i want that right button should do the next saved radio station. my steering wheels up down button does the same thing what the circle right and left. its very hard to control radio with my steering wheel buttons. is that possible?

You can do either track skip/station skip or preset skip/ no track skip. You can not do both.

no it does not change preset channel
