The poison worked fine now, I downgraded the GTK to version 2.16 and this solved the problem.
I'm trying to proceed without doing any modification to the nav software (in this case I suppose to see the military base icon instead of the speed cam), I already have the mk4 v32, so I burned the new dvd and it successfully worked in my navigation but the military bases didn't appear on the map, do I have to select some option on the nav screen in order to make the military bases appear on the map or it should appear directly without any selection?

Many thanks for your support.
