hi just one question,i got a 2005 leon fr 1.9 tdi,i have put jvc radio in it but everytime i turn off the ignition & then put it back on i lose all radio stations & setting. the cable which came with the radio has a bullett conector on each of the red & yellow wires,so which do i connect up,because if i put yellow to yellow & red to red i lose all memory,thanks
