How to get street by street track

Installed this wonderful software in my NC 15. It is working. But, somehow, track is drawn as bird flight routes. How can I get a track drawn street by street? It must be an setting problem.

Thanks.

AFAIK, no. The map is just a background layer and not something the .gpx tracks interact with.

But this sounds like you have a big problem with your GPS accuracy, as otherwise it should be pretty close to the streets.
