Struggling to input radio code on 2008 Multipla. Any help please. VDO Radio.

I don't have a VDO, but there are user manuals in the downloads section (link at top of page, then scroll down to multipla - im too new to be allowed post the link) which tell you how to put the code in.

Can someone help? I need a code for multiple radio fiat. serial number bp333152236051
