Help with retro radio blaupunkt

I found this in the golf I'm breaking





Does anyone know if a cd changer is compatible?

I don't know but wouldn't you just plug it into the aux socket?

Does that say DMS on the tape flap? (Disc Management System if I remember correctly) so if it does...yes!

it will or may have a din plug on the rear

take some pictures of the rear for me and i shall be able to tell

Pic of thE back



It says dnr on the tape flap

Do you know why it just comes up with this when turned on

Not sure but seems not to recognise the card or something

Looks as though it requires a code.Maybe there is a sequence of buttons you need to press once the code card is inserted into the radio.

Ok I have the code but wont let me enter anything, none of the buttons seem to do anything

Is there a time delay on entering the code?

I know on some you have to wait like an hour grrrrr

Possibly time delay or maybe the code has been entered incorrectly to many times and item is now locked. Requires specialist help in that case….

Entered code and works great
