After a really long wait I decided to upgrade my v28 to v29. Only problem I had was that the modification I made to the startup image was not done properly. Just redid it correctly and it worked.

During the failure I did however notice that the software although it did not have the nav menu, had everything else... looking like the a E90 nav (my car is a E46)

Which brings me to the question, there must be a way to fool the system to load the E90 color/lookandfeel for the E46 display. Does anyone have an idea?
