A bit of a long shot really !! I have got a Siemens NCDR1100 head unit , Bose speaker pack and colour 7"fujitsu ( ithink) screen as a manufacturer optional extra ( Vauxhall) in my Astra Coupe. I would like to add a DVD player of description to the setup , can it be done ? if so , can anyone reccomend one, and any other relevant kit i might need? Has anyone attempted this before, or could reccomend a specialist who might be able to help ? all help gratefully appreciated !!
