Thank's for the replies..... I have opted for this system as I'm not keen on cutting the dash! Also the radio was only 46 euros on German ebay.... so in my opinion, exellent value.
I was just after clarification on the type of computer, and wiring, as it seems very confusing, and I was not sure which I should be looking out for, as details of this system are hard to come by.
I have installed the radio, and connected it to another ebay bargain , BMW genuine ipod interface ,and in my opinion seems to offer far superior sound to that of the standard business radio that I had originally fitted.
I shall contact the dealer for the wires, and wait for the computer to turn up!
Thank's again
