how can i fix my car300 blaupunkt radio cassette in a vauxhall corsa?

Firstly , make sure that you have the CORRECT CODE. Then what you have to do is to start the Code Entry procedure by pressing a button (AS ?) plus the ON swith and leave it undisturbed until it unlocks, then enter the code , press the relevant button ( AS?) which should produce a beep and all should be OK. You may have to leave it for over 11 hours depending on how many wrong codes have been entered. (note: If your radio switches off automatically after an hour or so in the car, then it will have to be removed from the dashboard and set up on a workbench. Connect a battery + and - plus a speaker (to listen to the beep of the correct code) and leave it overnight. If it gets disturbed during this waiting period, then you will have to start again. This does work , but you have to be patient. Beware: The CAR300 has a separate display unit so if you do have to use the workbench method, (and enter the code "blind" ie without the display , then the first press of the button when entering a code changes the display from -(dash) to 0 (zero)...so a code of 1030 equates to pressing each button with an extra push.This means 1030 translates to .2141 "pushes "

if you have the original handbook there should be an unlocking code on it. if not, its more sense to buy a new radio than to unblock your old one
