First there were a BV6-22 and a BV6-26 (from 2003, I think), just a television with one DVI input. Then Beo made a BC6 - a 23"- and a 26" model - with built in radio - that`s why they call it "Beocenter". As add on you could order a DAB modul for the radio or a DVB modul. Now they make a Beovision 6 again (6-26). No radio, but HDMI input, if I remember correctly. You can have more info on the products site.....and hundreds of manuals when upgrading to gold....
