Hi, I have a 1994 (e34) 520i SE (airbag). It is fitted with the digital analogue clock and 'low level' dash without the check control panel. What I would like is to upgrade to the OBC, High level dashboard and obc control stalk. I know people have fitted the OBC to this model but i dont know whether anyone has retrofitted the higherspec dash stalk and OBC. If anyone could help me out i would really appreciate it. Also, if anyone could tell me what is required and possibly part numbers it would be great. Cheers. Steve
