doesn't match with this, but i've downloaded the the bmw professional maps, burned onto a DL DVD, and used on the car. i found this disk very noisy and always spinning, when the original is noiseless. the route planner is incredibly slow and some times i had to eject the disk and reload because it says: error in the dvd map disk.

i burnt the disk in 2x speed, had got no error burning and no error verifiyng the disk. any other with the same issue ?
