Got it, but don't know how to enter it. Any help? (Peugeot/Clarion PU 9534A)

Thanks

Switch ignition onto ACC position,enter code,then press button with Tune.a.me?(or something like that).That should work provided you didn't enter the code 3? times without any result(i think it's 3 times),otherwise the radio will be locked....Hope this helps...
