i assume OUpiel would have supplied a grundig or philips. switch on the ignition and radio. there are buttons 1-6 to store stations. if the first digit of the code is is 5, push the (1) button until 5 appears on the display. repeat with the correspoding number and button. then hold down FM button. if this does not work use the station memory buttons in the sequence of the code and hold down FM.
