cd player not working

[run_pug]

I just took the dashboard out of my corsa to replace steering column and now after refitting everything my cd player wont work.

It will eject the cd but do nothing else, the only thing i changed was disconnecting the airbag to fit a sports steering wheel

Any help would be appreciated

Pull it out and make sure the ISO connectors are all connected and working. Make sure that none of the fuses have blown in the sterio itself and in the main fuse board of the car
