But i have another question , is it normal that my bmw doesn't read my DVD + DL VERBATIM ? i have dowloaded the bmw high 2012 and my bmw is from 2002/2003 so it's the V32 firmware installed . Am I wrong ?? because DVD DL is read from V31 on MKIV readers
U'r unit is not MK4 but NAVI02 - start of prod. end 2002 (may be NAVI03 - from 04/2005). If you did not make any s/w upgrade - it is certanly not V31 or 32.
It is very common that such old units (2002-2004) do not read even Single Layer DVD. So do not try DL. Try SL. If it will not work - try CD from thread Europackage - VDO Dayton non C-IQ CD-Pack v.2012/2013
But if you wand DVD map - change your laser lens (SF-HD4 black cover).
