    JVC unit keeps resetting when ignition is off

    Hello,

    My JVC KD-R731BT keeps resetting the options I have set (colour, brightness, demo mode, ect) apart from the radio stations when I turn my ignition off. I installed the iso connecter that came with the unit to my car, as stated in the manual. It works fine apart from that. Any help is appreciated. Thanks

    One of the power wires (yellow I think) needs to be connected to a constant 12V source otherwise the HU will lose it's memory when you shut off ignition.

    Thanks. Changed red and yellow wires over and it's sorted.
