I asked a while ago how i could get the code for my original Alpine stereo in my Daimler XJ40. Well after a bit of searching i came across DND Services Ltd on the net. After looking down their list of cars, i found the '91 XJ40 and filled in the online form. I then kept my fingers crossed and forked out £10 via Paypal. Low and behold within 24 hours they had emailed me a code, which i duly typed into the head unit. To my relief it worked first time. I am a very happy man.
I thoroughly recommend DND Services if you need to get a radio code. Hopefully i'll never need their services again, but one never knows.
