Your Garmin help, please

For each course you download you need to set the course attributes, I would suggest something like this.

By default turn guidance is off, there is no way to turn it on as a global setting. Another garmin quirk.

Hmm. Just navigated across the city no problems. Downloaded a gpx from RWGPS and it gave me two warnings before turns, with te road names and arrows and such. When I went off course it recalculated pretty fast... Maybe it's set up right as default?

Edit: I don't use any garmin software to install the files, just dragged them into the gpx folder.
