On my headunit, you hold down the "Func" button while the headunit is off... you should get a menu come up... I found it out by reading the instruction manualOriginally posted by Fosgate
The deck is KEH-M8250, its an old tape player that has CD-Changer support.
So how do you get in to this hiden menu?
I`m not sure if it works on all pioneer HU's
