Just put in a Kenwood KDC-PSW9527 and on the display it says "Demo Mode" and I can't get rid of it, and theres nothing in the manual about it, also I can't enter the pin number, this conected?, anyone know how to get round this?

Cant quite remember exactly how to do it but i think you hold down preset number 4 then press the reset button but keep button 4 held down while its resetting and that should bring it out of demo mode but if not it could be one of the other presets 1-6
