My 206 has a clarion radio casset and a 5 disc cd player in the boot also a display unit on the top of the dash , i had the code number but nothing would would show on the display , and the radio would not respond to any button pressed , if you press the left button on the display unit ,till you get to radio it will tell you if it is working ? if not turn off the ignition , then lift up the cover from the back off the display unit complete with hazard switch , remove the 2 screws holding the display unit and disconnect the plug by pushing lever to the R/H side , for a few seconds , reconnect and turn on the ignition , you should then be asked to enter your code number you will then asked to set the country.time,date. etc , it worked for me
