MK4 can't read burned BMW Road Map Europe DVDs

[niimii3011]

Hi,

Im new to this forum. And im struggeling for days with the bmw navigation road map europe 2009-2 en 2010-1.

I have E39 2002 with a mk4 updated software to v32.

I have downloaded:
BMW Road Map Europe HIGH 2009-02 and the
BMW Road Map Europe HIGH 2010-01

I have burned to multiple DVD-R, Philips, Verbatim. With UltraIso and ImgBurn with 1x 2x 4x speeds but the disc isnt readable only the original BMW 2004-1 HIGH.

I was wondering if im doing something wrong? Or do i have not a good iso file. Cause when i open the original one there is 1 file in the root of ~2GB and in the 2009 and 2010 there is a DB folder with 2 large db_0 and db_1 files about ~2GB and ~1.4 GB and a folder with DVD9 also in the root.

Can anyone help me please?
