My wife just bought a 2004 Kia Optim (the "a" fell off). I was "programming" the radio buttons and got four of them done when she told me to get my dirty sweaty self out of her pretty little shiny white car. Afterwards, I can't get the remaining two buttons programmed/set on her radio. It is the standard AM-FM w/CD with 6 button resets for AM and FM. There are no instructions re: the radio in the operators manual. Anyone got any ideas how I can set her radio buttons to her favorite stations?
