I cannot get my kdc mp235 to got to aux mode.

Go to the stand by screen an hood the menu button down( second button from the left on the bottom) use the seek toggle on the right to go thru the options(up and down). When u get to the aux hit right or left on the toggle to turn it on.

In standby mode press and hold bass boost/menu button to open options menu. use direction pad to toggle thru options. push center button in middle of direction pad to enter each option for adjustments clock adj, etc...

I have the answer for this problem...finally! This is by far the dumbest instruction manual ever. Here goes:
while in standby mode, push and hold down the menu button until the display changes. Once the menu is up, toggle thur (using the am/fm toggle) until you come to AUX OFF, now toggle it to AUX ON. Exit the menu. Plug in your ipod and push the SRC button until AUX is displayed and enjoy.

You have to go into the standby menu and turn aux on. Go to standby, push menu button and scroll down to aux and turn on

i have a kdc 135 and i had the same problem. you have to go to standby mode, then hold down the menu button until MENU appears. then toggle up or down with the button on the right and it will say aux. then toggle left or right to turn aux on/off and then after that when you hit source it will come up as an option.

when its on standby hold the menu button and then use the right nob to change aux on then press menu again and src untill aux shows. hope this helps

ya press src until it gets to standby then hold the menu button until it says menu. then press the toggle button down until you see aux and press the toggle to the right to turn it on and be sure to press menu again to set it.

Yes i had a very similar problem.

I have the MP-235. I could not edit my clock, my subwoofer settings werent active, and I could not switch to AUX.

If you have these problems, you have to hold down the menu button (bass boost) to enter the menu. then scroll around, turn AUX on, change the clock, etc etc.

You turn demo mode off the same way. Kinda silly how they have it all set up.

Hope that helps anyone in the future. i just wasted 3 hrs with this crap!

Once in standby you have to press and hold the button to get into the menu. Once in the menu, you use the joystick control on the right to navigate to "Demo" and toggle it to "off" (can't remember off the top of my head... you either have to press the joystick in and hold it to toggle or just move it up/down...). Once done, just press Source to exit.
