unscrew the two screws underneath the heater dials on the dashboard, and take out the little ashtray thing and unscrew the screws behind there
carefully pull off that bit of the dash there will be a few wires hanging on it for the hazard lights and stuff so leave it slightly hanging to your oposite side.
unscrew the manfuacture standard casette/radio and pull it out, unwire it from the back, use the adaptor you should have bought (seperately) (halfords = £13.99 i think) for your panasonic cqc1475n and plug one end of that adaptor to the cars standard plugs what you just took the standard radio out of, and plug the other end into the wires of the panasonic head unit,get an aerial iso >din adaptor i think it's called and plug iny our aerial cable to the panasonic, screw everything back up how it was before but this time with the panasnoic, and you are sorted.
