I apologies for, probably silly question, but is it true that in order to get 2010 maps with red cameras to work i have to have a modified v32?

Maybe a bit offtopic but i'm stuck with the follwoing situation:
1. I have x3 06 with MKIV v32 it works with 09 unmodified maps. ( it's not the original disk so i can't say "original maps". )
2. i picked up 09 with red cameras here on forums and 10 w/o cameras. 09 with cams doesn't fit on the 4.7 DVD and the 10 is not working.
I would appreciate any help, please
