Hi, just brought a Clio Campus on 55 plate but sterio dosn't work. Took it out and found plugs out, so put all in. It just bleeps when I press the RH side button. Don't have a user guide, so not sure how it all works...No sound.!! gutted!! Does anyone have a user guide they could scan and send me on user controls, fault finding etc..or a website>>>looked everywhere.!! many thanks if you can help me...
