radio

just had my espace in the garage to have a gearbox fitted after it imploded on the M1. problem is I've no radio code and now no radio .I've only had the car 5 weeks and got no books with the car so I'm stumped.What little paperwork I got doesn't have the code. The dealer I got the car off doesn't have the code ..so what's my next move? I've had the radio out to see if it's written on the labels
