i have an 08' is250 when using an mp3 cd, i press the folder list to go through alpabetically since i put them into folders, if i am driving i can't go through the folders it's only when i am at a complete stop. I can only go through one by one to get to the folder i want. i can't just go from folder 2 and then press 25 i have to keep just pressing seek 23 times. does anyone know how to change this default? thanks
