I have a chipped UK ST3 self tuning box and cable for sale. You can get a map specific to you car from Chipped UK (check with them for prices) These retail at about £399 from the website (ST3 Intelligent Self Tuning System�Chipped UK).
I'm looking for £150 for the lot (including postage). I'll have a look for the CD as well but not sure if I have it so you might have to get direct from ChippedUK. PM me if interested.
