. The Serial Number is normally listed in the Audio Guide that came with the car . However to remove the radio you will require a pair of extractor keys (Available on Ebay or elsewhere) to insert into the 4 holes on the front fascia of the radio in order to release the securing clips
. You could try using 4 pieces of coathanger wire/small screwdrivers/allen keys or even 4 darts but it is a fiddly job without the proper extractor keys as all four have to release all 4 securing clips at the same time . (An assistant is also useful pulling the radio out whilst you are fiddling about with the extractors)
