Either you are using the wrong code, inserting it incorrectly, or the radio has locked up because you tried the wrong code too many times. Turn the radio on and just drive. After awhile it will unlock and you can try the code you have again. Reply back on my message board if this does not work and I will tell you how to get the code for free.

You need a special card to connect your radio to kanto's radio frequencies.
Cant you have to replace the entire radio

If the display is out, but the radio operates otherwise, the radio has failed.
