mapping inhformation is supplied to Mercedes-Benz on a regular basis and periodically a new disc is bought out. The chances of us noticing these updates are pretty slim and contrary to the literature, I have found it sometimes takes years for new roads to appear.
The owners of the mapping software try to say they have cars out on the roads which keepfeeding in new information, but I dread to think what information is fed into the system as it took an eternity for the M6 Toll Road to be added and I got fed-up with being told my main dealer was only a few miles away
