Hi,

if you've got a GPS device with you you can give either the exact coordinates or some other information about where you are and need help. This can be done via the help option in your device's menu. That way it could also be said at the intersection of two roads and in which direction if it is a multi lane road (i.e. A6/A5 in direction of Heidelberg) and you'll be able to navigate directly to that location.

I agree that it could be easier for all helping people to be able to navigate to just a ramp of the motorway but if given the coordinates or the second road of that intersection you'll be able to navigate there just as easy.

Regards

Lars.
