Today tried out the GPS with the new Nokia N85. On a walk with my daughter I tracked the two small parks between Ebertystraße and Hausburgstraße. Additionaly some footways in a park at Hausburgstraße. The first two parks are in the urban canyons of Berlin. Old buildings with flats and low distance between the buildings. As expected the track was not good. The waypoints in the last park were still better - lower buildings and much more distance between them.

I use Nokias Sports Tracker (1.82). The programm supports export to the GPX format.

See the trace.
