Thanx for the reaction! I have entered the code on my manual and didn't get an error. Now only the beeps. So I wanted to set the code to 0000 for entering the code again but I can't get it to 0000. I used the 2 and 5 preset button or the + and - on the steering manual, but that didn't work. Then I loosed my + pole of my battery for a while, but that only made my clock blinking. The radio is still 'normal', only with the beeps every 3/4 seconds. I'm sorry, but I am not familiiar to the terms 'VIN code' and 'electronical linked'. What does that mean?
VIN coded means that your car's VIN number has to be entered electronically into your radio's memory chip so that the radio is security tied to that particular vehicle .
This means that it cannot be fitted into another vehicle without being electronically linked to this new vehicle.
This is a job for your Main Dealer or a better option is a Radio Decoding Service
