Dodgy mk4 DVD nav computer?

aston rover · 19th January 2007, 14:52

Started to do the whole nav hardware upgrade thing as it seems to be the 'in thing' at the moment! Got hold of a BMW MK4 DVD nav computer from ebay (from this country), installed it today, but with no success.
The bordmonitor displays the ==BMW== logo for a short time, then the screen goes blank. This happens repeatedly. Every so often the nav menu is displayed (in colour) for a split second then vanishes. Put my Rover MK3 drive back in and it works perfectly.

Is there something I'm doing wrong with the MK4 unit or does it sound faulty? Part number is 65 90 - 6 920 182-01

Thanks in advance
