Many thanks for your response.

For some months now I navigate extensively with gpsapp and anytime I have a chance to compare to another commercial navigation-system I try to.

I have inspected the VDO solution as well as an original BMW navigation system. Both of them were not capable of speaking the roadnames (even if that would be great). Both of them give a first information 1000m ahead ("further on turn left" or something like that) , a second info 200m ahead ("in 200m turn left") and the last info when reached the turn ("now turn left"). That info would be a great help even if the roadname would be a perfect solution.

So the simple solution with samples sould be at least as good as most of the commercial products.
