can someone please help to locate the code? (nothing to do with Armani!!?)?

hi, code needed for Renault Scenic (07) stereo. battery replaced by nice man fro the RAC, car now starts but stereo not want to play anymore! if anyone can provide a code to make it work again would be v.v. grateful.....fed up of trying to serch online, downolad this, disable pop ups that, pay us 3.95 the other etc etc etc...
stuff on the back of the unit says......
8200 562 686 - -B
8200562686T
z354-SECURITY
RNEDAG70011216
RENRDW346-19
BS0207050011216

If that gibberish means anything to anyone & from it you can produce a code to make the stereo work again (my stereo in my car that I own which Renault UK insist they do not have records of stereo codes for with out a small charge.......hmmmm!), I and my entire family would be more than a little indebted to you! I await a reply with a maggot in my mouth! (bated breath....)
