I have the comand APS DVD based Nav in my W164 ML and I simply cannot rely on it to take me on the best/quickest route, even with a 2010 Map disc and the settings turned on correctly.

I have literally seen it tell me to make left and right turns, only to end up at the same place further along (which is deviating from the most direct route)

Any ideas?

It depends on the quality of the coding for that country. You have to use your own personal understanding of the terrain.
