I have a Pioneer CD Reciever stereo in my car and when I tried to use the directions in the manuel to set the clock it didnt work. The model number is DEH-1900MP. It says to press function and then use the side arrow keys to choose to reset the hours and minutes but that didnt come up. Instead it came up with other options. Does anybody know how to fix this? I was pressing the function button on the far right side on the very bottom, its silver. Maybe thats not what im supposed to be pressing? Help me please!
