Panasonic CQ-DF 783 memory problems
 

ok i hook my panasonic cd player in my car but when i hook the the battery wire from tha cd player to my battery wire on my wire harness the unit would not come on so i hooked the power wire from the cd player to that ignition wires the unit will come on but will not keep any memory and stuff so on tha battery wire from tha cd player it has battery 15a so i thought someone might had cut the fuse part off so i tried hookin a fuse up to it still didn't work so i am wondering if my problem is my power wire on my wire harness?
