Thank you for getting back to me, you were more fortunate then I.
I have attached a few pictures with this message so that you can see what I am up against.
So far I have replaced the entire center console and underside of the dashboard, I also have replaced what I think is the correct brackets.
However, as you will be able to see from the pictures I still have a bit of work to do as the remaining parts do not see to make sense. Hence my call for help, I would prefer to restore the stereo to BMW original with CD player instead of the tape player.
I will have a look at the other page you have mentioned and see where we go from there...........
